Frequently Asked Questions

What is the difference between the Fisher Space Pen Cap-O-Matic and a regular ballpoint pen?

The Fisher Space Pen Cap-O-Matic uses a pressurized nitrogen cartridge that forces out a special thixotropic ink. This ink is solid at rest and liquefies only when writing. Unlike standard ballpoint pens, it writes in zero gravity, underwater, at extreme temperatures, and at any angle. Ordinary pens rely on gravity to feed ink to the tip, which makes them unreliable under unusual conditions. The Fisher Space Pen writes up to three times longer than standard ink and doesn’t run out in the middle of a sentence.

At what temperatures does the Fisher Space Pen 775-R work?

The Fisher Space Pen Cap-O-Matic 775-R works reliably in a temperature range from -34°C to +120°C. This makes it suitable for outdoor use in cold winter conditions, as well as in hot environments. It does not freeze or leak, which sets it apart from most standard pens. It is precisely this feature that makes it the tool of choice for military personnel, firefighters, construction workers, and outdoor enthusiasts.

What type of cartridge does the 775-R model use, and can it be replaced?

The Fisher Space Pen 775-R comes with a Fisher SPR4 refill—black in color, medium line width. The refill is replaceable and compatible with the entire Fisher SPR Cartridge series. Replacement is easy and requires no tools. Using genuine SPR series refills ensures that all of the pen’s technical specifications are maintained.

Is the Fisher Space Pen Cap-O-Matic 775-R a good gift?

Yes, this pen is an excellent choice for a gift. It comes in a gift box, ready to give. It’s suitable for men and women in various professions—doctors, lawyers, military personnel, police officers, engineers, teachers, business leaders, and high school seniors. It has an interesting history tied to the space programs of NASA and the USSR, making it a great conversation starter. The combination of practicality, durability, and aesthetics makes it a gift with real value for everyday use.

What is the history of the Fisher Space Pen, and what is its connection to NASA?

Paul S. Fisher of Fisher Pen Co. developed a special pen for use in space without funding from NASA. The company invested approximately 1 million U.S. dollars from its own funds. In 1965, Fisher offered the pens to NASA, and in 1967, after rigorous testing, they were approved for use by the Apollo mission astronauts. About 400 pens were purchased at a price of $6 each. In February 1969, the Soviet Union also purchased 100 pens and 1,000 refills for use on Soyuz spaceflights. To this day, American astronauts and Russian cosmonauts continue to use the Fisher Space Pen.

This warranty is further confirmation that the Fisher Space Pen is a tool designed to last a lifetime.
