Fisher Space Pen Chrome Clip for #400 Series

Fisher Space Pen is the brand that put a reliable ballpoint in the hands of NASA astronauts. Paul C. Fisher developed a sealed, pressurized refill so ink flows when ordinary pens fail—upside down, through grease, in heat and cold, and in zero gravity. Decades later, Fisher still manufactures many models in the United States to the same demanding standard.

This Fisher Space Pen uses the brand's pressurized refill technology—engineered to write upside down, underwater, through oil and grease, and across a wide temperature range. Quality construction and a legacy tied to the U.S. space program make it a standout choice for EDC, professional use, and gifting.
