Space Shuttle Discovery materials:

Hardin Penworks, LLC, certifies that material supplied to the artisan of the accompanying hand-crafted item was sourced from the Space Shuttle Discovery, NASA’s Orbiter Vehicle OV-103.

The embedded upper cloth was sourced from the payload bay liner flown on the Discovery during the 7-day STS-82 mission. This mission was the 22nd flight of the Discovery and the 82nd mission of the Space Shuttle program. It was the second mission to service the Hubble Space Telescope. The crew repaired and upgraded the telescope's scientific instruments, increasing its research capabilities and achieved the highest altitude ever attained by an STS Orbiter, 335 nautical miles. The embedded lower red material is from the payload bay door seal of multiple STS missions.

During nearly 27 years of service, the Discovery flew 39 missions, carried 252 crew members, orbited our Earth 4,808 times, traveled 148,221,675 miles, and spent 365 days, 22 hours, 39 minutes, and 33 seconds in space travel.

Material Vision & Turning Notes:

Discovery blanks pair the woven payload bay liner cloth from the record-setting STS-82 Hubble servicing mission with rich red material from multiple payload bay door seals. The layered textures and vibrant color accents create bold, eye-catching pens once turned and polished. Light, controlled cuts preserve the integrity of the aerospace materials, making these excellent choices for Jr Series, Sierra, or custom builds.

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 Endeavour materials:

Hardin Penworks, LLC, certifies that material supplied to the artisan of the accompanying hand-crafted item was sourced from the Space Shuttle Endeavour, NASA’s Orbiter Vehicle OV-105.

The embedded upper foil was sourced from an insulating blanket flown on the Endeavour during the 10-day STS-77 mission. This mission was the 11th flight of the Endeavour and the 77th mission of the Space Shuttle program. During the orbiter’s flight, the Endeavor crew performed microgravity research aboard the commercially owned and operated SPACEHAB module. The mission also deployed and retrieved the Spartan-207/IAE satellite and rendezvoused with a test satellite. The lower embedded material is foam tile from multiple shuttle missions.

During nearly 19 years of service, the Endeavour flew 25 missions, carried 173 crew members, orbited our Earth 4,671 times, traveled 122,883,151 miles, and spent 296 days, 3 hours, 34 minutes, and 2 seconds in space travel.

Material Vision & Turning Notes:

Endeavour blanks combine insulating blanket foil from the STS-77 microgravity research mission with foam tile from across the program, producing a beautiful interplay of metallic sheen and lightweight thermal material. These respond excellently to standard turning methods with feather-light passes to protect the delicate embedded elements. Turn them into standout Jr Series, Sierra, or custom pens that celebrate one of NASA’s most versatile orbiters.

Sierra embedded blanks with WWII North American Aviation P-51 Mustang aluminum wing material.

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

The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in April 1940 by a design team headed by James Kindelberger of North American Aviation in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters, but North American Aviation proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed.

The definitive version, the P-51D, was powered by the Packard V-1650-7, a license-built version of the two-speed two-stage-supercharged Merlin 66 and was armed with six .50 caliber AN/M2 Browning machine guns. P-51s were used by the USAAF's Eighth Air Force to escort bombers in raids over Germany. The RAF's Second Tactical Air Force and the USAAF's Ninth Air Force used the Merlin-powered Mustangs as fighter-bombers to ensure Allied air superiority in 1944.

The P-51 was also used by Allied air forces in the North African, Mediterranean, Italian and Pacific theaters. During World War II, Mustang pilots claimed to have destroyed 4,950 enemy aircraft.

During the Korean War, the Mustang had been redesignated F-51. It was the main fighter of the United States until jet fighters like North American's F-86 took over this role. The Mustang then became a specialized fighter-bomber. Despite the advent of jet fighters, the Mustang remained in service with some air forces until the early 1980s. After the Korean War, Mustangs became popular civilian warbirds and air racing aircraft.

These blanks are made using original aluminum from USAAF P-51D Mustang, serial number 44-14379. This P-51D 'Little Doc' was engaged in aerial combat with four German Me 262 jet fighters on April 5, 1945. After damaging one 262, Lt. Cowley in 'Little Doc' was hit, and Cowley bailed out. Though wounded, Cowley landed safely in Belgium and returned to his unit. This aircraft was excavated in 2006. The material is certified and distributed by Hardin Penworks, LLC. This material is guaranteed to be 100% Authentic.

Sierra and Bolt embedded blanks with WWII North American B-25 Mitchell aluminum wing material.

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

The North American B-25 Mitchell is an American medium bomber that was introduced in 1941 and named in honor of Major General William "Billy" Mitchell, a pioneer of U.S. military aviation. Used by many Allied air forces, the B-25 served in every theater of World War II, and after the war ended, many remained in service, operating across four decades. Produced in numerous variants, nearly 10,000 B-25s were built. These included several limited models such as the F-10 reconnaissance aircraft, the AT-24 crew trainers, and the United States Marine Corps' PBJ-1 patrol bomber.

Sierra embedded blanks with North American T-28C Trojan material.

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

The North American T-28C Trojan, a piston-engine military trainer, was a cornerstone of U.S. Navy pilot training in the post-World War II era. First flown in 1949 and entering service in 1950, it was designed to replace the T-6 Texan. Powered by a Wright R-1820-86 Cyclone engine producing 1,425 horsepower, the Trojan reached speeds of 343 mph and had a range of 1,060 miles. The T-28C variant, built for the Navy, featured a tailhook, shorter propeller, and reinforced structure for carrier landings, making it ideal for advanced training. Nearly 2,000 T-28s were produced, including 299 C models, training pilots in aerobatics, gunnery, and carrier operations. During the Vietnam War, some Trojans served in counter-insurgency roles. Its predictable handling and excellent visibility earned it the nickname “Pilot Maker.”

These pen blanks are crafted from the authentic fuselage skin of T-28C Trojan, Bureau Number 140597, preserving its legacy. Ideal for aviation enthusiasts, veterans, or collectors, they transform this trainer’s history into a unique writing instrument.

Bureau Number 140597 History: Accepted by the Navy in December 1956, BuNo 140597 served primarily with Training Squadrons Two (VT-2) and Three (VT-3) at NAS Whiting Field, Florida. In 1968, VT-3 set a record with 174 instructors and 162 T-28s, flying 110,000 instructional hours. Retired to the Military Aircraft Storage and Disposition Center in 1975, it was sold in 1982.

Sierra embedded blanks with Northrop B-2 Spirit metal material.

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

The Northrop B-2 Spirit, commonly known as the Stealth Bomber, is a cornerstone of U.S. Air Force strategic capabilities. Introduced in 1997, this subsonic, flying-wing aircraft was designed for stealth, enabling it to penetrate advanced air defenses undetected. Powered by four General Electric F118-GE-100 engines, each producing 17,300 pounds of thrust, the B-2 can carry up to 40,000 pounds of ordnance, including nuclear and conventional weapons. Its range exceeds 6,000 nautical miles without refueling, extendable with aerial refueling, making it a global strike platform.

The B-2’s stealth is achieved through its low-observable design, radar-absorbent materials, and advanced heat signature management. A notable component is the titanium upper engine exhaust shield, which mitigates the heat signature of the F118 engines. For instance, a section of titanium from such a shield, replaced due to in-flight cracking, highlights the material’s critical role in thermal stealth. This panel was later redesigned to enhance durability, reflecting ongoing improvements in B-2 maintenance.

With only 21 units built, each costing approximately $2.1 billion, the B-2 remains one of the most expensive aircraft ever produced. Operated by the 509th Bomb Wing at Whiteman Air Force Base, Missouri, it has seen combat in conflicts like Kosovo, Iraq, and Afghanistan, delivering precise, high-impact strikes.

These titanium embedded blanks are crafted from a Northrop B-2 Spirit’s upper engine exhaust shield, replaced due to structural cracking. The material is certified and distributed by Hardin Penworks, LLC, and is guaranteed to be 100% authentic.

Pre-tubed embedded blanks with Northrop P-61B Black Widow material.

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

The Northrop P-61 Black Widow is a twin-engine United States Army Air Forces fighter aircraft of World War II. It was the first operational U.S. warplane designed as a night fighter.

Named for the North American spider Latrodectus mactans, it was an all-metal, twin-engine, twin-boom design armed with four forward-firing 20 mm (.79 in) Hispano M2 autocannon in the lower fuselage, and four .50 in (12.7 mm) M2 Browning machine guns in a dorsal gun turret. Developed during the war, the first test flight was made on 26 May 1942, with the first production aircraft rolling off the assembly line in October 1943.

Although not produced in the large numbers of its contemporaries, the Black Widow was operated effectively as a night fighter by United States Army Air Forces squadrons in the European Theater, Pacific Theater, China Burma India Theater, and Mediterranean Theater during World War II. It replaced earlier British-designed night-fighter aircraft that had been updated to incorporate radar when it became available. After the war, the P-61 was redesignated as the F-61, and served in the United States Air Force as a long-range, all-weather, day/night interceptor for Air Defense Command until 1948, and for the Fifth Air Force until 1950. The last aircraft was retired from government service in 1954.

On the night of 14 August 1945, a P-61B of the 548th Night Fighter Squadron named Lady in the Dark was unofficially credited with the last Allied air victory before VJ Day. The P-61 was also modified to create the F-15 Reporter photo-reconnaissance aircraft for the United States Army Air Forces and subsequently the United States Air Force.

George Washington's Mount Vernon Vintage Stamp with Pecan Wood

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

Mount Vernon is a historic national landmark and former plantation of the first president of the United States, George Washington and his wife, Martha. The estate is on the banks of the Potomac River in Fairfax County, Virginia. It is located south of Washington, DC and Alexandria, VA and across the river from Prince George's County, MD.

The Washington family acquired land in the area in 1674. Around 1734, the family embarked on an expansion of its estate that continued under George Washington, who began leasing the estate in 1754 before becoming its sole owner in 1761.

The original mansion was built around 1734 by George Washington's father, Augustine. George Washington expanded the house twice, once in the late 1750s and again in the 1770s. It remained Washington's home for the rest of his life. Following his death in 1799, under the ownership of several successive generations of the family, the estate progressively declined as revenues were insufficient to maintain it adequately. It wasn’t until 1858 that the house’s historical importance was recognized and saved from ruin by the Mount Vernon Ladies' Association.

The pecan tree featured below was removed in Jan 2014 due to the risks of the tree damaging the Mansion. George Washington did not plant this tree. He didn't have any trees of this size close to his home. It is believed the pecan tree was planted about 60 years after he passed away, around 1860, making it an estimated 154 years old. The tree stood approximately 145 feet tall and weighed an estimated 50 tons.

Mount Vernon was memorialized with a 1½¢ stamp on February 22, 1956. The Mount Vernon stamp illustrates a picturesque view of Washington's home facing the Potomac River.

Sierra and Bolt embedded blanks with RAF F.4 Buzzard wood .

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

The Martinsyde F.4 Buzzard was developed as a powerful and fast biplane fighter for the Royal Air Force (RAF), but the end of the First World War led to the abandonment of large-scale production. Fewer than 400 were eventually produced, with many exported. Of particular note was the Buzzard's high speed, being one of the fastest aircraft developed during World War I.
