The pressurised ink cartridge of the Fisher Space pen allows you to write at any angle, in extreme temperatures and in zero gravity (the Astronaut pen was used on many space missions). The Bullet pen is the flagship product, fitting neatly into a pocket and on permanent display at the New York Museum of Modern Art. We think it makes a great gift for gadget lovers, keen travellers or a best man. The bullet pen comes with or without a clip, in a deluxe version with rubber grip or stylus (the Capacitive). We stock the thixtropic ink refill, enabling the pen to write 3 times longer.
