Fisher Space Pen
Fisher invented the Space Pen technology in 1965. They've been used in space since 1968. Fisher Space Pen’s Sealed Pressurized Ink Cartridge performs in temperatures from -30ºF to +250ºF, 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.
