Russian Space Pen

When NASA first started sending astronauts into space, they realized that the ball-point pen would not work at zero gravity. A million dollar investment and two years of tests resulted in a pen that could write in space, upside down, on almost any surface and at temperatures ranging from below freezing to over 300 Degrees Celsius. When confronted with the same problem, the Russians used a pencil. This Russian Space Pen is a replica of the writing instrument used by Soviet Cosmonauts on early manned space flights. The Russian Space Pen measures 7 in. long, writes upside down, at zero gravity, in extreme temperatures & on almost any surface.
