30-day Money Back GuaranteeHow many times have you reached into your flight bag or kneeboard during a flight only to find the ink has dried or the pen no longer working? This happens even more frequently the higher altitudes that you fly. The Fisher Space Pen is your solution to always having a working writing instrument during flight and on the ground.
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.
And they did. 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 these pens is over 100 years.
This retractable Zero Gravity Space Pen features a rubberized, cushioned barrel and grip. Gift boxed. Includes Fisher PR4, black ink, medium point.

A: In 1968 Fisher Space pens were first used on Apollo 7 after two years of testing by NASA.
The space race was on, and the astronauts involved in the Mercury and Gemini missions had been using pencils to take notes in space since standard ball points did not work in zero gravity. The Fisher cartridge did work in the weightlessness of outer space and the astronauts, beginning with the October, 1968 Apollo 7 mission began using the Fisher AG-7 Space Pen and cartridge developed in 1966.
