Fisher Space Pens have a really interesting history. In 1945, Paul Fisher, a scientist, wanted to create a pen that was dependable and superior in writing, quality and style. He succeeded in 1967 when the first Fisher Space Pen went into space! It's special feature over other pens, is the fact Fisher Space Pens have a pressurized refill with special ink that allows it to write over fingerprints, under water, upside down, on wet paper, in freezing cold and extreme heat (and of course in space). There is no leaking and Fisher Space Pens last up to 3 times longer than normal ballpoint pens! These make a great gift for the Man or Woman that has it all. It could even make a really neat graduation present.
