U1F - Blue Ink Fine Point Fisher Pressurized Universal Cartridge

Point Size: .9mm Ball

Packaging: Refill Cartridge Blister Card

Fisher Space Pen’s Sealed Pressurized Ink Cartridge performs in temperatures from -30º F to +250º F, underwater, in zero gravity, at any angle–even upside down! The ultimate in dependability!

The choice of ski patrols, search and rescue teams, law enforcement agencies, armed forces, and everyone who demands reliability in a writing instrument.

This is a specialized cartridge used in our Q4 Multi-Action Space Pen.

Please note: The ‘U’ (Universal) Cartridges contain a much smaller amount of ink, they write about 1200 feet depending on your writing style, as compared to our regular PR Cartridge which should write more than 12,000 feet depending on style and surface. The 'U' cartridge is not interchangeable with the 'PR' cartridge.
