Sierra embedded blanks with Lockheed SR-71 Blackbird titanium material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The Lockheed SR-71 "Blackbird" is a long-range, high-altitude, Mach 3+ strategic reconnaissance aircraft developed and manufactured by Lockheed Corporation. It was operated by both the United States Air Force and NASA.

The SR-71 was developed as a black project from the Lockheed A-12 reconnaissance aircraft during the 1960s by Lockheed's Skunk Works division. The shape of the SR-71 was based on that of the A-12, which was one of the first aircraft to be designed with a reduced radar cross-section. Mission equipment for the reconnaissance role included signals intelligence sensors, a side-looking airborne radar, and a photo camera. The aircraft was introduced to operational service in January 1966.

SR-71 is made of 92% titanium, a metal or rutile. It was in short supply in the United States, and the Skunk Works team was forced to look elsewhere for the metal. The major supplier of the ore was the USSR. Working through Third World countries and bogus operations, they were able to get the rutile ore shipped to the United States to build the SR-71.

During missions, the SR-71 operated at high speeds and altitudes of Mach 3.2 and 85,000 feet to allow it to outrace threats. If a surface-to-air missile launch was detected, the standard evasive action was simply to accelerate and outfly the missile. A total of 32 aircraft were built; 12 were lost in accidents with none lost to enemy action. The SR-71 was retired largely due to political reasons in 1988; several were briefly reactivated during the 1990s before their second retirement in 1998. NASA was the final operator retiring them in 1999. As of 2020, the SR-71 continues to hold the world record it set in 1976 for the fastest air-breathing manned aircraft.

These blanks are made with titanium material embeds from the wreckage of SR-71 'Super Skater' serial number 17970. This aircraft was lost on 17 June 1970 following a re-fueling collision with a KC-135Q tanker. The material is certified and distributed by Hardin Penworks, LLC. This material is guaranteed to be 100% Authentic.

Sierra embedded blanks with Lockheed U-2 Dragon Lady aluminum wing material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The Lockheed U-2, nicknamed "Dragon Lady", is an American single-jet engine, high altitude reconnaissance aircraft operated by the United States Air Force and previously flown by the Central Intelligence Agency. It provides day and night, high-altitude, all-weather intelligence gathering.

Lockheed Corporation originally proposed it in 1953, it was approved in 1954, and its first test flight was in 1955. It was flown during the Cold War over the Soviet Union, China, Vietnam, and Cuba. In 1960, Gary Powers was shot down in a CIA U-2A over the Soviet Union by a surface-to-air missile. Major Rudolf Anderson Jr. was shot down in a U-2 during the Cuban Missile Crisis in 1962.

U-2s have taken part in post-Cold War conflicts in Afghanistan and Iraq and supported several multinational NATO operations. The U-2 has also been used for electronic sensor research, satellite calibration, scientific research, and communications purposes. The U-2 is one of a handful of aircraft types to have served the USAF for over 50 years, along with the Boeing B-52, Boeing KC-135, and Lockheed C-130. The newest models, TR-1, U-2R, & U-2S, entered service in the 1980s, and the latest model, the U-2S, had a technical upgrade in 2012.

U-2, serial number 1078, was built as a TR-1A in March 1985. On April 24th, 1990, this aircraft crashed at RAF Alconbury in the UK, with no fatalities, and was subsequently rebuilt as a U-2ST trainer.

This aluminum relic is from the original section of 1078’s outer wing skin paneling, and it was recovered from the scene of the 1990 accident.

This titanium material is from the wreckage of SR-71 'Super Skater' serial number 17970. This aircraft was lost on 17 June 1970 following a re-fueling collision with a KC-135Q tanker. The material is certified and distributed by Hardin Penworks, LLC. This material is guaranteed to be 100% Authentic.

Sierra embedded blanks with original aluminum frame fragments of the Hindenburg Luftschiff Zeppelin #129.

All blanks will come with one COA per blank. 
COAs are 4" x 6" card stock with foil COA seal.

Here is a macro-specimen of duralum (aircraft grade aluminum) cut from the wreckage of the famous LZ-129 Zeppelin der Hindenburg! This is NEWLY FOUND MATERIAL just released from the Frazier Collection! Acquired at an estate sale in Germany a few years ago. We know of its tragic loss in 1937 at Lakehurst, New Jersey. What we don't know is why! And most likely never will... This specimen is a small world-class piece embedded in Royal Palm.

LZ 129 Hindenburg (Luftschiff Zeppelin #129; Registration: D-LZ 129) was a large German commercial passenger-carrying rigid airship, the lead ship of the Hindenburg class, the longest class of flying machine and the largest airship by envelope volume. It was designed and built by the Zeppelin Company (Luftschiffbau Zeppelin GmbH) on the shores of Lake Constance in Friedrichshafen and was operated by the German Zeppelin Airline Company (Deutsche Zeppelin-Reederei). The airship flew from March 1936 until it was destroyed by fire 14 months later on May 6, 1937 while attempting to land at Lakehurst Naval Air Station in Manchester Township, New Jersey, at the end of the first North American transatlantic journey of its second season of service with the loss of 36 lives.

Sierra embedded blanks with McDonnell Douglas F-4B Phantom II material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The McDonnell Douglas F-4B Phantom II, a twin-engine, all-weather fighter-bomber, was a mainstay of U.S. naval aviation. First flown on May 27, 1958, and entering service in 1960, it was renowned for its versatility and power. Powered by two General Electric J79-GE-8 engines, each producing 17,000 pounds of thrust, it reached speeds of Mach 2.2 and had a range of 1,600 miles. Its 38-foot wingspan and armament, including AIM-7 Sparrow and AIM-9 Sidewinder missiles, plus up to 16,000 pounds of bombs, made it lethal in air-to-air and air-to-ground roles. The F-4B saw extensive action in Vietnam, flying over 5,000 sorties for the Navy and Marine Corps, and set multiple speed and altitude records. Its rugged design and distinctive shape earned it the nickname “Rhino.”

These pen blanks are crafted from the authentic fuselage of F-4B Phantom II, Bureau Number 148369, preserving its combat legacy. Perfect for aviation enthusiasts, veterans, or collectors, they transform this iconic aircraft into a timeless writing instrument.

Bureau Number 148369 History: Delivered in 1961, BuNo 148369 served with Marine Fighter Attack Squadron 542 (VMFA-542) during the Vietnam War, flying combat missions from Da Nang Air Base in 1965. It later operated with various Navy squadrons before retirement. Sourced from the Flying Leatherneck Aviation Museum, its materials carry the scars of service.

The McDonnell Douglas F/A-18A Hornet, a twin-engine, all-weather, carrier-capable multirole fighter, redefined naval aviation with its versatility. First flown on November 18, 1978, and entering service in 1983, the Hornet, nicknamed the "Rhino," was designed for both air-to-air and air-to-ground missions. Powered by two General Electric F404-GE-402 engines, each producing 17,700 pounds of thrust, it achieves a top speed of Mach 1.8 at 40,000 feet. Its digital fly-by-wire system, the first in a production fighter, ensures exceptional maneuverability. The F/A-18A carries a 20mm M61A1 cannon and up to 13,700 pounds of weapons, including AIM-9 Sidewinder, AIM-7 Sparrow, and AGM-65 Maverick missiles. During Operation Desert Storm, Hornets demonstrated their prowess by shooting down Iraqi MiG-21s and bombing targets in the same mission. With a 6,000-hour service life and robust design, it served the U.S. Navy, Marine Corps, and allies like Canada and Australia, including the Blue Angels from 1987 to 2020.

These pen blanks are crafted from materials of F/A-18A Hornet, Bureau Number 162437, preserving its legacy. Ideal for collectors, veterans, or aviation enthusiasts, they transform this combat-proven aircraft into a functional heirloom.

Bureau Number 162437 History: Delivered in 1986, this F/A-18A served with distinction, notably with the Blue Angels as aircraft #5. It flew combat missions and later performed in airshows, showcasing the Hornet’s agility. After retirement, its materials were repurposed for these unique pen blanks, honoring its storied service.

Metropolitan Stadium (often referred to as "the Met", "Met Stadium", or now "the Old Met" to distinguish from the Metrodome) was a sports stadium that once stood in Bloomington, Minnesota, just outside Minneapolis. The Minneapolis Millers minor league baseball team played at Met Stadium from 1956 to 1960. The Minnesota Twins and the Minnesota Vikings then played at the "Met" from 1961 to 1981. The North American Soccer League soccer team Minnesota Kicks also played there from 1976 to 1981.

The area where the stadium once stood is now the site of the Mall of America.

The Hubert H. Humphrey Metrodome (commonly called the Metrodome) was a domed sports stadium located in downtown Minneapolis, Minnesota. It opened in 1982 as a replacement for Metropolitan Stadium, the former home of the National Football League's (NFL) Minnesota Vikings and Major League Baseball's (MLB) Minnesota Twins, and Memorial Stadium, the former home of the Minnesota Golden Gophers football team.

The Metrodome was the home of the Vikings from 1982 to 2013, the Twins from 1982 to 2009, the National Basketball Association's (NBA) Minnesota Timberwolves in their 1989-90 inaugural season, the Golden Gophers football team until 2008 and the occasional home of the Golden Gophers baseball team from 1985 to 2010 and their full-time home in 2012. It was also the home of the Minnesota Strikers of the North American Soccer League in 1984. On January 18, 2014, the Metrodome roof was deflated, signaling the beginning of demolition work. The Vikings played at the University of Minnesota's TCF Bank Stadium for the 2014 and 2015 NFL seasons, ahead of the planned opening of U.S. Bank Stadium in 2016.

The stadium had a fiberglass fabric roof that was self-supported by air pressure and was the third major sports facility to have this feature (the first two being the Pontiac Silverdome and the Carrier Dome). The Metrodome was similar in design to the former RCA Dome and to BC Place, though BC Place was reconfigured with a retractable roof in 2010. The Metrodome was reputedly the inspiration for the Tokyo Dome in Tokyo, Japan. The stadium was the only facility to have hosted a Super Bowl (1992), World Series (1987, 1991), MLB All-Star Game (1985) and NCAA Division I Basketball Final Four (1992, 2001).

The Metrodome had several nicknames such as "The Dome", "The Thunderdome", and "The Homer Dome." Preparation for the demolition of the Metrodome began the day after the facility hosted the final home game for the Minnesota Vikings on December 29, 2013, with actual demolition beginning on January 18, 2014. The Metrodome was torn down in sections while construction of U.S. Bank Stadium began.

NASA Apollo 11 blanks.

All blanks will come with one COA per blank. 
COAs are 4" x 6" card stock with foil COA seal.

Blank Tube Size Descriptions:

• Jr Series blanks are double tube set 12.5mm tubes and 10.5mm lower tubes

• Sierra Clone blanks are single 27/64" tubes

• Custom single Tube or Double Tube Sets available. (Two Week Delivery) Specify tube size needed in notes at check out.

Apollo 11 was the American spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, and Armstrong became the first person to step onto the Moon's surface. Aldrin joined him, and they spent about two hours fifteen minutes together exploring the site they had named Tranquility Base upon landing. While Armstrong and Aldrin collected 47.5 pounds of lunar material to bring back to Earth, pilot Michael Collins flew the Command Module Columbia in lunar orbit. Armstrong and Aldrin were on the Moon's surface for 21 hours, 36 minutes before lifting off to rejoin Columbia.

Apollo 11 was launched by a Saturn V rocket from Kennedy Space Center on Merritt Island, FL, on July 16, and it was the fifth crewed mission of NASA's Apollo program. The Apollo spacecraft had three parts: a command module with a cabin for the three astronauts, the only part that returned to Earth; a service module, which supported the command module with propulsion, electrical power, oxygen, and water; and a two-stage lunar module — a descent stage for landing on the Moon and an ascent stage to move back into lunar orbit.

After traveling three days until they entered lunar orbit, Armstrong and Aldrin then moved into Eagle and landed in the Sea of Tranquility on July 20. The astronauts used Eagle's ascent stage to lift off from the lunar surface and rejoin Collins in the command module. The astronauts returned to Earth and splashed down in the Pacific Ocean on July 24 after more than eight days in space. The Apollo 11 space capsule was recovered by the USS Hornet (CV-12).

This piece of Kapton foil is from a larger section removed from the lunar lander prior to launch, due to a defect in a squib valve. To remove and replace the valve, some of the Kapton thermal blanket had to be removed and replaced. Since this piece was removed prior to launch, it did not fly in space or to the moon. It was an original part of the lunar lander, Eagle, and a fine artifact from the historic Apollo 11 mission.

USS Hornet (CV-12) is an Essex-class aircraft carrier built for the United States Navy (USN) during World War II. After service during both the Korean War and Vietnam War, Hornet was the recovery ship for the Apollo program for both the Apollo 11 and Apollo 12 missions to the moon. She was eventually designated as both a National Historic Landmark and a California Historical Landmark, and she opened to the public as the USS Hornet Museum in Alameda, CA, in 1998.

These blanks were crafted using materials from an original US Postage Stamp #479100 and original Kapton foil from the Apollo 11 lunar lander Eagle, and a wood relic from the deck of the USS Hornet (CV-12). The materials used are certified and distributed by Hardin Penworks, LLC. This material is guaranteed to be 100% Authentic.

Space Shuttle Challenger materials:

Hardin Penworks, LLC, certifies that material supplied to the artisan of the accompanying hand-crafted item was sourced from the Space Shuttle Challenger, NASA’s Orbiter Vehicle OV-099.

The embedded space flown materials are foam tile from multiple shuttle missions and paperwork from the STS-8 mission. Challenger was used for numerous civilian satellite launches, and it also used to repair a malfunctioning telescope. On its 10th flight in January 1986, Challenger disintegrated 73 seconds after liftoff killing the crew of STS-51-L. An O-ring seal in one of the solid rocket boosters failed to contain pressurized burning gas that leaked out of the booster causing a structural failure of Challenger's external tank and the orbiter's subsequent disintegration.

During its three years of operation, Challenger was flown on 10 missions in the Space Shuttle program, spending over 62 days in space for a total of 1,496 hours. Completing 995 orbits around Earth, Challenger traveled 25,803,939 miles.

Material Vision & Turning Notes:

Challenger blanks feature authentic foam tile from multiple missions paired with original STS-8 paperwork, offering a unique mix of lightweight thermal protection material and historical flight documents. These embedded pieces turn beautifully with standard techniques—use light cuts to avoid chipping the foam while revealing the rich history within. Perfect for creating Jr Series, Sierra, or custom pens that honor the legacy of America’s space program.

Finish Recommendation:

For the ultimate mirror-like shine that highlights every detail of the space-flown materials, we recommend our Magic Juice Polishing Compound.

Space Shuttle history:

The Space Shuttle was the first operational orbital spacecraft designed for reuse. Each Shuttle was designed for a projected lifespan of 100 launches or ten years of operational life, although this was later extended.

Each Space Shuttle was a reusable launch system composed of three main assemblies: the reusable orbital vehicle (OV), the expendable ET, and the two reusable solid rocket boosters (SRB). Only the OV entered orbit shortly after the tank and boosters are jettisoned. The vehicle was launched vertically like a conventional rocket, and the orbiter glided to a horizontal landing like an airplane, after which it was refurbished for reuse. The SRBs parachuted to splashdown in the ocean where they were towed back to shore and refurbished for later Shuttle missions.

Five operational OVs were built: Columbia (OV-102), Challenger (OV-099), Discovery (OV-103), Atlantis (OV-104), and Endeavour (OV-105). A mock-up, Inspiration, currently stands at the entrance to the Astronaut Hall of Fame. An additional craft, Enterprise (OV-101), was built for atmospheric testing gliding and landing; it was originally intended to be outfitted for orbital operations after the test program, but it was found more economical to upgrade the structural test article STA-099 into orbiter Challenger (OV-099).

Space Shuttle Columbia materials:

Hardin Penworks, LLC, certifies that material supplied to the artisan of the accompanying hand-crafted item was sourced from the Space Shuttle Columbia, NASA’s Orbiter Vehicle OV-102.

The embedded lower black material was sourced from a nose gear tire flown on the Columbia during mission STS-28. This mission was the 4th mission dedicated to the Department of Defense and the 8th flight of Columbia. The embedded upper cloth was sourced from the payload bay liner flown on Columbia during the 10-day STS-109 mission. This mission was the 108th mission of the shuttle program, the 27th of the orbiter Columbia, the 4th servicing the Hubble Space Telescope, and the last successful mission of the Columbia before the ill-fated STS-107 mission disaster in Feb. 2003.

During nearly 22 years of service, Columbia flew 28 missions, carried 207 crew members, orbited our Earth 4,808 times, traveled 125,204,911 miles, and spent 300 days, 17 hours, 40 minutes, and 22 seconds in space travel.

Material Vision & Turning Notes:

Columbia blanks showcase the deep black of a flown nose gear tire from STS-28 alongside the textured payload bay liner cloth from the historic STS-109 Hubble servicing mission. The combination delivers striking visual depth and tactile contrast that polishes to a stunning finish. These blanks respond well to sharp tools and light passes, making them ideal for Jr Series, Sierra, or custom shuttle-themed pens destined to spark stories of exploration and resilience.
