Fisher Space Pen

Fisher Space Pen is a legendary name in the world of writing instruments, renowned for its ability to write in zero gravity, underwater, over grease, and in extreme temperatures. Developed by Paul C. Fisher in 1965 and later used by NASA astronauts, the Space Pen is more than just a pen — it’s a symbol of innovation, durability, and American engineering. Whether you’re writing in space or simply signing documents on Earth, a Fisher Space Pen delivers unmatched performance and reliability.

Why Choose Fisher Space Pens?

Fisher’s patented pressurized ink cartridge was a game-changer. It enables writing:

  • At any angle — even upside down
  • In extreme hot and cold conditions (-30°F to +250°F)
  • On wet or greasy surfaces
  • In zero gravity environments (yes, it went to space!)

Each pen is made in the USA with an emphasis on quality, precision, and craftsmanship. Built to last, they’ve become the choice of not just astronauts, but outdoor enthusiasts, military personnel, engineers, and writers around the world.
