Paul Fisher, designed the Bullet pen in 1948, and it has featured in the New York Museum of Modern Art as an outstanding example of “exquisite industrial design”, for many years now. We like the fact that it's appeared in an episode of Seinfeld and that it was the pen used on the Apollo 11 mission to fix the arming switch. All Fisher Space Pens write underwater, upside down, and for twice as long as other roller ball pens, used by astronauts, cosmonauts and ourselves.
