Fisher Space Pen Apollo 13 Cap-O-Matic Pen, Green/Brass. FP775G-13-50

This Special Edition Cap-O-Matic Space Pen has the same pressurized ink refill cartridge used on the Apollo 13 Mission - It defies gravity, writing in the gravity free vacuum of space, and of course, at any angle here on Earth. It writes in the harshest of temperatures (-30 to +250 degrees F) and environments including under water, through grease, on almost any surface, lasting three times longer than an average pen, and is still used on all manned space flights today.
