Fisher Space Pens
 |
Unlike ordinary ball pens which rely on gravity to feed ink, the replaceable Space Pen cartridge is pressurized. At nearly 35 pounds per square inch, ink is continuously fed to the tungsten carbide ball, allowing the user to write at any angle, even upside down. This advanced technology required Fisher Space Pen Co to develop a new and special ink.
The new visco-elastic, thixotropic ink, with a consistency similar to that of very thick rubber cement, flows as a result of the shearing action of the rolling ball in its socket. This shearing action liquefies the solid gel thixotropic ink, allowing the pen to write smoothly and dependably on the most surfaces and even underwater. Evaporation, wasted ink and back leakage are eliminated. The estimated shelf-life of our pens is over 100 years.
