The Shuttle Space Pen is the next installment to our line of Astronaut pens, it was introduced during the Space Shuttle Program and is the current pen of choice of the astronauts on the ISS today. The CH4 is proudly produced in the USA Each is made of solid brass with hard chrome plating. The CH4 is thinner and lighter than its predecessor the AG7, with a slightly more sleek and modern appearance.

This side button has a substantial sound and feel to it, ensuring that you will always remember to retract the point before sliding the pen back into your pocket.
