Fisher Space Pen INFINIUM Ballpoint Pen—Durability and Style in One

The Fisher Space Pen INFINIUM series is designed for people who value quality. Whether you work in an office or outdoors, this pen combines style, comfort, and exceptional reliability.

The casing is made of brass with a gold-colored titanium nitride coating—one of the hardest and most abrasion-resistant coatings available. The same coating is used in the medical field for implants and in the aerospace industry.

The refill is built-in and non-replaceable—designed to last a lifetime under normal use. The ink is thixotropic: it is solid at rest but liquefies when writing. The pen does not skip or leak.

Inside the cartridge is a pressurized nitrogen gas cartridge that keeps the hermetically sealed ink under pressure. That is precisely why it writes at any angle, underwater, and in extreme temperatures.

A Brief History of the Fisher Space Pen

During the early NASA missions, astronauts used pencils. In 1965, Paul S. Fisher designed a pen that works in zero gravity, underwater, and at extreme temperatures. The development was funded entirely by the company—approximately $1 million in its own funds.

After rigorous testing, NASA equipped the Apollo mission astronauts with these pens in 1967. About 400 pens were purchased for the project at a price of $6 each. In February 1969, the Soviet Union also purchased 100 pens and 1,000 refills for the Soyuz missions. To this day, American astronauts and Russian cosmonauts continue to use the Fisher Space Pen.
