Fisher Space Pen Retractable Cap-O-Matic Black Barrel with Stylus

This Cap-O-Matic retractable pen from Fisher Space Pens features a black barrel and clip. The legendary Fisher Space Pen ink cartridge that comes with the Cap-O-Matic was originally developed for NASA in 1965, but you'll likely be more impressed that it will continue to write in freezing cold, boiling heat, underwater and at any angle -- even upside down!
