Pilot FriXion Zone retractable erasable rollerball. The Pilot FriXion Zone uses the same brilliant thermosensitive ink as the rest of the range. It erases cleanly and completely simply via the heat generated by the friction of the eraser on the top of the pen. Hidden under a screw-on cover, the eraser avoids getting in the way of the retract mechanism, which is instead actuated by the pocket clip. The Zone features an all new V-shaped ring, an elastomer grip and a smooth body. All barrel colours fitted with blue ink refill. Refill with Pilot BLSFR refills available in a variety of ink colours. Did you know? : FriXion ink reappears after being erased if you put the paper in the freezer for a few minutes...
