.375 Cartridge Space Pen

Crafted from genuine spent .375 shell casings, these distinctive pens transform ammunition materials into functional pieces designed to be used and appreciated for years to come. Each casing carries its own unique character, making every pen a one-of-a-kind piece of repurposed history.

Fitted with a reliable Fisher Space Pen cartridge, these pens are rugged enough for the field yet refined enough for the office—built for wherever life takes you.

Each pen comes packaged in its own miniature gun case, making it a unique, ready-to-gift piece for collectors, military enthusiasts, outdoorsmen, or anyone who appreciates craftsmanship with a story.

Fisher Space Pens are built for more than just outer space. The fact is, due to the patented sealed and pressurized ink cartridge, they will write in just about any condition and on almost any surface. Underwater or over grease. In extreme temperatures (-30 to +250 F/-35 to +121 C). Upside down or floating in a gravity-free zone. It doesn’t matter, our pens will perform. Our sealed and pressurized ink cartridges last three times longer than the average pen with an estimated 100-year shelf life.
