Fisher Space Pen Black Fine Pt. Pressurized Refill

Fisher Space Pen Black Fine Pt. Pressurized Refill. Blister card packaged. Blue ink, fine point. Made in the USA.

The Fisher Space pen was invented by Paul C Fisher in the 1960’s, and was subsequently adopted by the American and Russian space agencies. Before the space pen, astronauts used grease pencils and plastic slates. The pressurized ink cartridge allows the user to write in zero gravity, upside down, underwater, over wet and greasy paper, at any angle and in extreme temperature ranges. A sliding float separates the ink from the pressurized gas, and the ink is forced out by compressed nitrogen. It has been claimed that Fisher Space Pen refills can write for 3 times longer than a standard ballpoint pen.
