Fisher Space Pen Military Pen
Made especially for the U.S. armed forces, this rugged pen can write nearly anywhere, on nearly anything.
The Fisher Space Pen Backpacker pen writes in extreme temps from -30degF to 205degF. And it writes underwater, upside down, at any angle, over grease and for 3 times longer than most pens.
This pen combines a compact, stowaway design with a pressurized ink cartridge that allows the pen to write nearly anywhere, on anything.
Use this pressurized ink cartridge to refill your Fisher Space Pen(R).
