Fisher Cap-O-Matic Yellow Chrome Ball Pen with Stylus

The Cap-O-Matic Space Pen utilizes cap activation to extend and retract the point, and each carries a pressurized PR style ink refill cartridge, which means that they offer all of the unique capabilities that are synonymous with Fisher products: they will write upside down – at any angle, under water, through grease, extreme temperatures (-30 to +250 degrees F), on almost any surface, three times longer than the average pen, and of course in the gravity free vacuum of space, and all of our pens are lifetime guaranteed for quality against all manufacturing defects. The stylus portion of your pen is easily replaced by unscrewing it from the body. This replacement part is considered a disposable item and is NOT covered under our repair or replacement policy.
