The famous Fisher "Bullet" Space Pen is a compact, convenient writing instrument that allows you the ease of writing under any conditions. This is not like your standard everyday pen that is reliant upon gravity to write, this unique writing instrument forces ink through the cartridge at three times the atmospheric pressure to a carbide ball at its tip for bold, smooth results with each stroke. Fits easily in pockets, purses, or briefcases yet becomes a full-size writing instrument. Most of the astronauts and NASA flight crews prefer the bullet pen.
Writes upside down and at any angle
Writes twice as long as other roller ball pens
The most dependable, reliable, and versatile pen in the world
The Fisher Space pen ink cartridge is the key to its superiority. It is pressurized with 35 pounds per square inch of gas. This pressure pushes on the sliding float ball allowing our unique thixotropic ink to flow smoothly in the tungsten carbide ball.
