The Boker iPlus TTP Tactical Pen features a rubber tip for use on touchscreens, while being well protected under the screw-off rear cap. As usual, the front, large cap conceals a standard ball point pen tip, compatible with Parker giant refills or Fisher Space Pen refills. The milled aluminium body of the Tactical Tablet Pen has an additional engraving surface. Please note that the pen comes apart with a counterclockwise thread to exchange the refill. This prevents unintended disassembly of the pen when unscrewing the cap.
