In 1968, Apollo 7 set off on an 11-day trip to orbit the Earth. Along with the rest of their gear, each of the mission's Astronauts were given a single pen. But not just any pen - it was Paul Fisher's Anti-Gravity 7. Five decades later, every manned NASA mission still includes Fisher Space Pens as part of their loadout. But now, much to our gratification, they also produce their lifetime-guaranteed all-conditions writing utensils for the general public.
