Fisher Space Pens have been trusted by NASA astronauts since 1967 and are still used aboard the International Space Station today. Every Fisher pen uses a sealed, pressurized ink cartridge that writes reliably in any orientation, in extreme temperatures, underwater, and in zero gravity. Made in the USA from solid brass and aluminum, Fisher offers a range of styles from the compact Bullet to the classic AG7 Astronaut to the one-hand Cap-O-Matic. Whether you need a pen for your pocket, your toolbox, or your field kit, Fisher builds it to work when other pens won't.
