A Brief History of Stadium Pen Blanks
Founded in 2010, Hardin Penworks branched off to form Stadium Pen Blanks in 2018. SPB was formed when we noticed a need for quality Certificates of Authenticity. Slowly over time, SPB has amassed a highly specialized collection of 200+ certificated pen blanks from stadium seats, benches, walls, & floors. SPB also has a wide variety of historical building, aircraft, and nautical solid wood blanks. SPB’s extensive collection of embedded blanks includes historical, sports memorabilia, & cultural blanks as well.
