The Pilot FriXion Zone rollerball pen uses the same brilliant thermosensitive ink as the rest of the frixion ball 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 with a minimalist barrel design.Comes with the new premium refill with a 350m writing capacity! 100m more ink than standard refills.All barrel colours are fitted with a black ink refill.Refill with PilotFR7 refills available in a variety of ink colours.Learn more about erasable ink and how it works here.
