Additional Info

Fisher Pens are the ultimate in dependability. Environmentally friendly, Fisher Pens are guaranteed to perform in temperatures from -30 to +250 degrees F, underwater, in zero gravity, in elevations up to 12,500 feet, and at any angle. Each has an ultra-hard Tungsten Carbide ballpoint precisely fitted in a stainless steel socket to prevent leaks and deliver constant, uniform ink flow. Fisher pens use thixotropic ink (a semisolid ink until the shearing action of the rolling ball liquefies it) in a hermetically-sealed, pressurized reservoir with a sliding float to separate the ink from the compressed nitrogen. Lasting 3-times longer than ordinary ballpoints, Fisher Space pens are hand-tested and carry an unconditional lifetime guarantee.

Fisher Pen Brand Story

In the 1950's there were dozens of ballpoint models, and nearly every one took a different refill. So in 1953 Paul Fisher invented the "Universal Refill," which could be used in most pens. But he didn't stop there. After much experimentation he perfected the refill using thixotropic ink; the trick was to have the ink flow when you wanted it to, and not to flow the rest of the time, a problem Fisher solved.
