FriXion Ball® Erasable Gel Pens write smoothly and erase cleanly, so you can erase every 'oops' (the written ones, at least). Offering unlimited do-overs, you can write, erase and re-write until you get it right, without any wear or tear to the paper or messy eraser crumbs. The heat generated by erasing friction turns the unique thermo-sensitive gel ink clear, so your marks simply disappear from the page. Mistakes are a thing of the past with FriXion. Now nobody needs to know it wasn't perfect the first time! Stylish, ink-color-matched barrel features a cushioned, dimpled grip on one end and an included eraser on the other as well as a snap-tight cap.
