Fisher Space Pens

The Fisher Space Pen, invented by Paul Fisher, is a marvelous writing instrument that you can take anywhere, even outerspace! Designed with a nitrogen pressurized ink catridge and equiped with a thixotropic ink-semisolid that only liquifies through the shearing action of the rolling ball, the Fisher Space Pen can be used in the freezing tundra and the scorching hot desert. The Space Pen works so well that it has been used in dozens of NASA missions and continues to be the pen of choice for astronauts. Go far out with a Fisher Space Pen from ALKO office supply!
