FISHER-TEC All weather, All conditions Space Pen.

U.S. astronauts and Russian Cosmonauts always use genuine anti-gravity Fisher Space Pens because they write in space and even better on the earth or under water! The secret – a sealed nitrogen pressurized J5 ink cartridge with extremely close tolerances that feeds the ultra-hard tungsten carbide ball point. Writes like a fountain pen with the smoothness of a rollerball with the convenience of a ballpoint. Ink flows smoothly at any angle, upside down, under water, over grease and fingerprints, on photos in extreme heat or cold. Guaranteed to write three miles and will store for 100 years without drying out.
