This custom black-ink Flying Eyes ballpoint pen twists to open and has a bunch of extra features, including a soft rubber stylus that twists off to expose a double-pointed screwdriver (one side is Phillips and the other is a Flat Head), a level, and two rulers (inches and centimeters).
The screwdriver itself is a lifesaver in a pinch! Now you can represent Flying Eyes and have a helpful tool always handy in your cockpit.
