Bullet Pen Black w/Space Shuttle

The famous Fisher "Bullet" Space Pen is a compact, convenient writing instrument that allows you the ease of writing under any conditions. Unlike standard pens that are 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. Some of the astronauts and NASA flight crews prefer the bullet pen.FEATURES:Writes underwater 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 worldThe 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.
