The iPlus TTP 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 ballpoint pen tip, compatible with Parker giant refills or Fisher Space Pen refills. The milled aluminum 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.
