Celebrate America’s National Mammal with the officially licensed Smithsonian Bison: Standing Strong Tornado™ Rollerball. Inspired by the Smithsonian’s Bison: Standing Strong exhibition, this design honors the bison’s place in American history and the Smithsonian’s early role in efforts to preserve the species.

Bison are acid-etched into a stonewashed copper barrel for a timeworn look reminiscent of a vintage American coin. Stonewashed pewter trim complements the rugged finish, with “Smithsonian” etched into the top ring and the iconic sun logo on the top disc. The pen arrives in a commemorative Retro 51 tube.
