The Fisher Space Pen Company has been a creative American writing company since the early 1950s. After inventing the first universal refill which could be used in most ballpoint pens Paul Fisher went on to create the first pressurized ballpoint pen refill. The Fisher Space pen refill was made of a special semisolid ink and then pressurized with nitrogen. This Fisher Space ballpoint pen was guaranteed to write upside down underwater and in extreme temperatures of hot and cold. Fisher Space pen has become the standard writing instrument used by American astronauts in space. This Fisher space ballpoint pen is extremely reliable and can be used in almost any condition.
