Fisher

In the 60s, the American Paul C. Fisher designed for NASA a pen that worked perfectly even in the most extreme conditions: extreme cold and heat, underwater, on any surface... Since then, millions of people have relied on these writing tools to do their jobs (astronauts, firefighters, underwater rescue teams, etc.) or simply enjoy the pleasure of writing with the only pen with a pressurized refill that allows an uninterrupted flow of ink in any circumstance or arrangement of the piece.
