Under what conditions does the Fisher Space Pen refill work?
The pen operates at temperatures ranging from -35°C to +121°C. It can write underwater, at any angle, and in extreme weather conditions. This is made possible by the hermetically sealed, pressurized ink reservoir and the tungsten carbide ball.
