The revolutionary Fisher Space Pen® Writes at any angle!

The combination of its pressurized cartridge and specially formulated ink allow it to write in temperatures from -30º to +250º F, underwater, upside down, in zero gravity – in short, just about anywhere. That's why the Space Pen, originally designed for the NASA astronauts, is the pen of choice for people who demand writing reliability. The Fisher Space Pen – the only pen that has been to the moon and back.
