The original Astronaut AG-7E is the pen THAT WENT TO THE MOON!! When astronauts started to explore the reaches of outer space, Paul Fisher realized that no existing pen could perform in its zero-gravity vacuum and temperature extremes, His common sense approach and practical experiments resulted in the invention of the sealer-pressurized Fisher AG-7 Anti-Gravity Space Pen. After rigorous testing, NASA selected the Fisher Space Pen for use on all of the Apollo missions. They are still used on manned space flights. Engraved with July 20, 1969 and Fisher logo to commemorate the first space flight! All Fisher Space Pens write in any angle, remain operational under all climatic conditions, write through water and in extreme heat ad cold, write in the gravity free vacuum of space, writes underwater and on wet surfaces! Comes in a beautiful gift box with guarantee and Fisher Space Pen story!
