Green Cap-O-Matic Space Pen with Plastic Barrel and Chrome Cap

The Cap-O-Matic line utilizes cap activation to extend and retract the point. They carry the same gas pressurized refills as nearly all of the other Space Pens, which means that they have all of the unique capabilities that you would expect from a Fisher pen: they will write upside down - at any angle, under water, through grease, extreme temperatures, on almost any surface, three times longer than the average pen, and of course in the gravity free vacuum of space.
