Fisher Space Pen Side Release Button Ballpoint Retractable Pen, Black Titanium Nitride (Ag7-BTN)

This is the original Fisher Space Pen that was used on the Apollo 7 space mission in 1968 after 2 years of testing by NASA and has been used on all manned space flights since then. The design and construction of this pen has not changed in 36 years. The pen you buy today is exactly the same as the one taken to the moon in 1969. It is a heavy pen and the weight rests reassuringly in your hand as you write. The Ag7-BTN is made from solid brass and has a black Titanium Nitride finish.

It has a very positive and substantial feeling click mechanism. You press down on the top to extend the refill and press the side button to retract the refill. Its special design assures you that youll always retract the point before.
