Astronaut Space Pen Gold/Blk

This 5.13″ pressurized pen writes reliably in zero gravity, underwater, over grease, and across extreme temperatures—conditions where conventional ballpoints fail. The solid brass body features a black Cerakote finish with gold titanium nitride accents and a hard gold titanium nitride nose tip. A side button retracts the tip, and the pen includes a pocket clip for carry. It uses Fisher’s Pressurized PR4 cartridge with black ink in medium point, and accepts any PR refill for future loading.
