The World’s Most Reliable Pen

With a lifetime of ink, titanium nitride body, and all-temperature, all-angle writing ability, this is the world’s most reliable pen. Created by Fisher Space Pen and used by NASA astronauts on every manned space flight since 1967, the patented pen contains high-viscosity thixotropic black ink that lasts three times longer than a standard ballpoint, so writers may never need to replace it. Price $149.95

Nitrogen gas sealed within the pressurized reservoir prevents leaks and enables the tungsten carbide ball to write cleanly in temperatures from -30° F to +250° F., whether the user is seated at a desk or floating weightless in space. Its lightweight, durable chrome exterior is accented with black Titanium Nitride and has a clip for fastening to a pocket or a space suit.

  1. This article is not true. I bought one of these, it worked great for about a week. Then it started leaking ink. I would take the cap off and before I could use it, i would have to wipe the excess ink off the tip. I notified the company, and they sent me a replacement which had the same problem. The best advice for using this pen is to not use it at all. Unless you like the look of ink on your fingers and excess ink on your paper.
