The Pilot Frixion Clicker 05 rollerball pen is the latest pen in the excellent Pilot Frixion range of erasable pens. It uses the same superior ink technology that allows you to write, erase and re-write using the rubber at the end of the pen whilst leaving no mess or residue.What makes the Pilot Frixion 05 Clicker different is that is a retractable pen with a clever way of advancing and retracting the nib. Unlike conventional pens that use a push button at the end of the pen this is achieved by pressing the pocket clip.The Pilot Frixion Clicker 05 pen has a 0.5mm tip, is available in seven colours and can be refilled. Available individually or further savings can be made buying in packs of 12.
