From the Fisher Archive, we have a limited number of Vortex Space Pens!
 
The Vortex Space Pen utilizes twist 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.
