Paul C. Fisher developed the pressurised 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 ballpoint and thixotropic ink in a hermetically sealed cartridge pressurised at nearly 35 pounds per square inch; allowing it to write in freezing cold, boiling heat, under water and at any angle – even upside down!

Available in blue or black medium point and comes complete with an adapter so as well as using this refill in your trusty space pen, you can fit this refill into most Parker style ballpoint pens too . . .
