The classic and timeless signature design of the Fisher Bullet Space Pen dates back to the 1940s and has often been imitated, but never duplicated. As well as being sleek and stylish, the Bullet Space Pen has an all-brass body with a chrome finish, resulting in a practically indestructible ballpoint pen. The included specially-formulated pressurized ink will write smoothly upside down, underwater, in extreme temperatures, and yes, even in space! When capped, this compact pen measures under 4", the perfect size to carry anywhere you may need it—the glovebox, toolbox, purse, or pocket.
