.375 Caliber Bullet Space Pen

The rugged Fisher .375 Caliber Bullet Pen is built to look like a .375 caliber rifle round. In fact, the cap is actually made from an authentic H&H .375 magnum shell. When opened, the pen fits back into the cap, giving you a balanced and sturdy writing instrument.

The ink cartridge used within all Fisher pens, including the .375 Caliber Bullet Pen, was designed for use in the zero gravity environment of space. The pressurized ink cartridge allows the pen to write at any angle, underwater, and even upside down. The specialized thixotropic ink writes three times longer than standard ink, in extreme temperatures, and even on top of grease and oil. Single black ink refills now available.
