FriXion is a brand of erasable gel pens created by Pilot Corporation. These pens use a unique thermosensitive ink that disappears when exposed to heat, allowing users to erase their writing by simply rubbing the tip of the pen against the paper. This feature makes them popular for note-taking, drawing, and other tasks where corrections are needed. In addition to pens, the FriXion line includes highlighters, markers, and mechanical pencils, all designed with the same erasable technology. The versatility and convenience of FriXion products have made them a favorite among students, professionals, and artists alike.
