Fisher - Ballpoint Pen - Space Pen - Cap-O-Matic - NASA Matte Black

Designed by Paul Fisher for the first manned Apollo mission in 1968, the Fisher Space Pen writes in zero gravity, underwater, at any angle including upside down, and in extreme temperatures.

The Cap-O-Matic uses cap activation to extend and retract the point. The body is all brass with a matte black finish, NASA logo, and matching clip. Made in the USA with a lifetime promise against manufacturing defects. Comes in a Galaxy Gift Box and includes a black medium ink cartridge. Replacement cartridges are available separately.

The refills are hermetically sealed, pressurised with nitrogen gas, and feature a tungsten carbide ballpoint tip. Fisher ink is a gel – thicker than liquid, similar in consistency to toothpaste – that only flows when pressure is applied to the ballpoint.
