The Cap-O-Matic line 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.
