The Shuttle Pen is now considered to be the pen of choice for the astronauts on the ISS today. Each Shuttle Pen is composed of solid brass with a shiny chrome finish, and all are produced in the USA. The Shuttle Pen has a modernized appearance and is both thinner & lighter than its predecessor, the Anti-Gravity Pen. 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.

Features:

Fisher Space Pens don't leak or ooze.
