Pilot FriXion Ball Plus 07 retractable erasable rollerball. FriXion Ball Plus uses the same brilliant thermosensitive ink as the rest of the range. It erases cleanly and completely via the heat generated by the friction of the eraser on the top of the pen. The eraser avoids getting in the way of the retract mechanism, which is instead actuated by the pocket clip. Features a triangular ergonomic grip area. Barrel contains 82% recycled plastic. Did you know?: FriXion ink reappears after being erased if you put the paper in the freezer for a few minutes.
