Fisher Space Pen PR Pressurised Ballpoint Refills

Fisher Space Pen refills are suitable for use in almost all Fisher Ballpoint Pens and come with a plastic adapter that allows this refill to be used in pens that use Parker "G2" type refills.
Paul.C Fisher developed the pressurized refill for Nasa in 1965. It's still in use today on manned space flights because it performs when other pens fail. The combination of tungsten carbide ballpoint and thixotropic ink in 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!
