Fisher Space Pen - AG7 Anti Gravity Space Pen "The Pen That Went To The Moon" - Silver Chrome

The Anti Gravity, or AG7, Astronaut pen was designed with the sole purpose of writing in zero gravity. The solid and firm construction is so reliable that the design has not been altered since 1968 when it flew into outer-space on the Apollo 7 mission.
