Writedeleterepeat with the retractable version of FriXion! Erases cleanly by friction-generated heat with the special FriXion eraser nub, leaving no debris. Uses the same ink to write and over-write. Using a thermosensitive ink, the FriXion Ball Clicker, loyal to Pilots tradition, revolutionises writing! It has a funky style with its tapered barrel and its tattoo decoration and comes in seven colours. Not to be used for signatures, legal documents, examination papers or other documents where writing needs to be of a permanent nature.
