A Brief History of Stadium Pen Blanks
Founded in 2010, Hardin Penworks branched off to form Stadium Pen Blanks in 2018. SPB was formed where a need was noticed to have quality Certificates of Authenticity. Slowly over time, SPB has amassed a highly specialized collection of 100+ certificated pen blanks from stadium seats, benches, walls, & floors. SPB also has a wide array of historical & nautical blanks as well as embedded historical & cultural blanks available.
