Bullet Space Pen, Blueberry

The Bullet Space Pen is a classic writing implement that’s truly out of this world. Originally developed by the Fisher Space Pen Company, this compact tool uses pressurized ink cartridges to allow smooth, dark lines in even the most extreme conditions. Whether you’re writing at an awkward angle, dealing with wet or greasy paper, scuba diving, or even floating in zero gravity, you can be sure that you won’t lose a letter. The Bullet Space Pen is compact enough to carry in a pocket, purse, or wallet, and comes in a custom-fit moonscape gift box. That’s one small step for man, one giant leap for your penmanship.

In the quest for a perfect ink refill, Paul Fisher developed a prototype that used thixotropic ink and a cartridge pressurized with nitrogen, so that it didn't rely on gravity to make it work. The result was a pen that was dependable in freezing cold, desert heat, underwater, and — of course — outer space. Beginning with the October, 1968 Apollo 7 mission, NASA began using the Fisher AG-7 Space Pen and cartridge, cementing the pen’s legendary status.
