The standard Fisher “SPR Series” Refills were developed for NASA and have been used on EVERY Space Shuttle mission both American and Russian. They are hermetically sealed with a specially formulated thixotropic ink and pressurized to about 35 PSI. They are the only refills that will write at any angle because they do not rely on gravity.

About Fisher Space Pen:

Fisher Space Pen is yet another great breakthrough from space research. No other pen has so much to offer. This pen was designed in 1965 by Paul C. Fisher, for NASA, and with no cost to NASA or our government. Ordinary pens rely on gravity to write. Hold them upside down and they quit. There was a need for a pen that would work in the zero gravity vacuum of space, and in extreme conditions. Paul Fisher developed such a pen. For the ink cartridge to write at any angle the cartridge was charged with 35 PSI of nitrogen. A small ball type float was used to separate the gas charge from the ink and it had to be hermetically sealed to hold the charge. With that type of pressure a precision fit stainless steel machined socket with a tungsten carbide ball and a specially formulated thixotropic ink was used keep the pen sealed and leak free. Fisher Space Pens have been used on EVERY Space Shuttle mission, both USA and Russian. They were also featured on a Seinfeld episode. ..... Imitated but never duplicated..... Because it is hermetically sealed it will not dry out like other pens and has a shelf life of over a hundred years. It does not rely on Gravity, It writes upside down, in the vacuum of space, on wet paper, underwater, in the freezing cold of -30° F, and the boiling heat of 250° F. Fisher Ink cartridges stay leak free and writing longer, cleaner, and more consistently than any other ink cartridges. Fishers are not only utilized by Astronauts but the Thunderbirds, the Blue Angels, the Navy Seals, and the Canadian Snowbirds also use the Fisher pen. Fishers are favorites among Firefighters, Paramedics, and Police Officers. 

If you count on a pen to work, you need a pen with a Fisher ink cartridge. The Fisher Bullet Pen was exhibited at the New York Museum of Modern Art. It has been featured on the Tonight Show, Good morning America, John Ratzenberger's Made in America, and an episode of Seinfeld.  Still proudly made here in the USA.
