Fisher Bullet Space Pen - Maroon 400M Keychain 63mm cap fits other NalgeneWhen closed, Bullet Space Pens are the perfect size to carry in your wallet, pocket, purse, car glove box, organizer or toolbox. When open it's a full sized, evenly balanced writing instrument. The original Bullet Space Pen was conceived in July of 1948, Paul Fisher was soon machining a new pen design shaped from solid aluminum. It became our first Fisher ball point pen, the 400 Bullet Pen, and arguably the most popular pen of the twentieth century.
