Fisher Space Pen
Founded by Paul C. Fisher, an American specializing in the production of precision bearings for WWII bomber planes, Fisher Space Pen is famous for revolutionizing the ballpoint pen industry. Its refills are pressurized with nitrogen gas, allowing users to write in any position, in varying temperatures and under water. In 1968 NASA approved the use of the Fisher Space Pen by astronuats in all missions in outer space. Grounded users can find practical applications for Fisher pens, also. This brand is manufactured in the U. S. A.
