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.
Designed to withstand the rigors of space travel, Fisher Pens have earned the reputation of a superior technical pen for all applications.
