Fisher Space Pen CH4

The American Fisher Space Pen has been producing its well-known ballpoint pens for many years. They were already used by NASA in the first manned launch of the Apollo programme in 1968. The CH4 is similar to the AG7 model with the same features, but the CH4 is a lightweight alternative to the aforementioned model. Press the top of the pen to advance the cartridge and the side button to release it.

The pressurised cartridge writes in rain, heat, cold, all angles and of course in space!
