Fisher Space Pen Cap-O-Matic Matte Black Medium Point Pen

The Cap-O-Matic is a 5.25″ pen with a pocket clip and medium point PR4 black ink cartridge. It writes upside down, at any angle, under water, over grease, and in extreme temperatures—capabilities that make it reliable in conditions where standard pens fail. The matte black finish includes a thin white line imprint.
