This pen is composed of solid brass with a matte black finish and chrome accents.  It features a unique dual-action knock mechanism that extends the tip via the knock on the end, with a release button on the side to retract it.  This side retract button has a satisfying sound and feel to it, ensuring that you will always remember to retract the point before putting the pen away in a bag or pocket.

Paul C. Fisher designed an innovative ballpoint pen that performs best in unique environments. He created a sealed and pressurized ink cartridge that debuted on the Apollo 7 mission in 1968 and has been reliably used on all manned space flights ever since.
