Originally developed for use by NASA astronauts, the Fisher Space Pen is the last word in writing dependability. Its the choice of ski patrols, search and rescue teams, law enforcement agencies, armed forces and everyone who demands reliability in a writing instrument...

Paul C. Fisher developed the pressurized refill for NASA in 1965, Its still in use today on manned space flights because it performs when other pens fail. The combination of tungsten carbide ball point and thixotropic ink is a hermetically sealed cartridge pressurized at nearly 35 pounds per square inch allows it to write in freezing cold, boiling heat, underwater and at any angle - even upside down!

Its the "go anywhere, write everywhere pen!"
