The Fisher Bullet Space Pen is the right pen for you if you are looking for a pen that can take on even the most extreme conditions. It is one of the most iconic pens ever made. This pen was designed by Paul Fisher in 1948, and was updated for NASA in the 1960s to withstand even the extreme conditions in space. The innovations incorporated in this pen include an ink cartridge that is pressurized with nitrogen gas and a super-hard tungsten carbide ballpoint tip which is precision fit to the ink chamber, to prevent seepage and the clicking sound that other cheaper ballpoint pens make. There is an o-ring at the base of the pen’s grip which ensures that it seals when capped. This protects the tip of the pen from any contaminants.
The pen can be used to write in a wide range of temperatures which can vary from -30º F at one end to 250º F on the other, underwater and over wet surfaces. It can also be used for writing at any angle, even upside down and in zero gravity. It fits easily into pockets thanks to its compact size and curved shape. It is made of brass and comes with three types of finish – matte black, raw brass, and chrome. The pen has an estimated shelf life of 100 years and is definitely a better choice than most other pens in the market.
