The Fisher Space Pen is 'the space pen'; the only pen ever to be used in space. The AG-7 'Astronaut' space pen was first used on the Apollo 7 mission, is the only pen that has been to the moon, and is still used today by all American, Russian, European and International Space projects.
Fisher produces a range of space pens all built around the Fisher pressurised refill. The refill uses a thixotropic ink which remains solid until 'stirred' by the ball point, a nitrogen gas plug ensures a steady flow of ink at any angle, hence, the pen is not reliant on gravity to draw the ink from the pen.
Fisher space pens write on glossy surface such as plastics and coated papers, they even write through grease and underwater. Fisher pens are capable of writing at extreme temperatures from -35 to 121 Celsius. They are also good for doing the crossword in bed!
Fisher produces several ranges of space pens; the renowned 'AG-7 Astronaut' pen, the slighter, retractable 'Shuttle' range and the iconic 'Bullet' space pen, which, has been awarded many design awards and displayed in the Museum of Modern Art.
