The Fisher Space Pen was selected by NASA for its unique capabilities and was used by Astronauts on all manned space flights. It writes in any position without stopping. Because the refill is sealed and pressurized, it allows you to write upside down, underwater, on glossy photos, over grease and in extreme temperatures, -50 to 400 degrees Fahrenheit.

The Space Pen ink cartridge is permanently sealed so that it cannot back-leak and the ink cannot evaporate, thereby increasing the shelf life to an estimated 100 years.
