Fisher Space Pen and refills

Paul Fisher, and American specialising in the production of precision bearings for World War 2 Bomber planes, did not imagine that one day in the future he would revolutionise the writing capability of the ball point pen... and with it, enable communication between astronauts in outer space.

Paul's mission began in 1945, with the realisation that the ball-bearing business would end along with the War. In his job search, he heard about a company seeking to produce a "ball point" pen. The pen company thus far had an unreliable pen; the only available refills allowed too much ink flow, leaked, or dried out too soon.

By 1950 Paul Fisher had not only solved the pen refill problems, he began his own production of ball point pens, further improving the performance of the refill and introducing the Bullet Pen.

Paul was positively passionate about his pens! A million dollars in research later, he invented a cartridge that would write in any position, thanks to a refill pressurised with nitrogen gas! Ink stained jackets and pants were gone for good, and a wonderful, smooth performing ball point pen was born.

Paul had another mission in mind for his pen - he introduced this unique pen cartridge to NASA! The Fisher Pen underwent extensive testing, and was subsequently approved for a trial mission in outer space. In 1968 the Fisher Space Pen was whole-heartedly approved and ordered for use by astronauts on ALL MISSIONS IN OUTER SPACE.

Stainless steel, precision-machined socket prevents leaks and oozing, yet delivers instant uniform ink flow.

Thixotropic ink in a hermetically sealed and pressurized reservoir writes three times longer.

Ink will not dry out for over 100 years! Writes under water or over grease at temperatures of - 45C to +121C.

Prior to flying on any operational mission all instruments must pass through a rigorous testing program. The Fisher Space Pen was tested for two years before being accepted by NASA.

Used on ISS International Space Station, Apollo Missions, and Shuttle Missions. Russian Soyuz and MIR Space Flights, ARIANE French Space Program.

Used during the Everest North Face Ski Expedition 1997.

Used in many professions including military and law enforcement.

Seen in the Guinness Book of records as "Most Versatile Pen".
