The FriXion line of pens write smoothly and erase cleanly so you can erase every ‘oops’. FriXion offers you unlimited do-overs so 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 causes our unique thermo-sensitive gel ink to become clear so the words disappear completely from the page. Now nobody needs to know it wasn’t perfect the first time! 
Writes Smooth, Erases Clean
Erase and rewrite repeatedly without damaging documents. No wear or tear!
Unique thermo-sensitive gel ink formula disappears with erasing friction*
*Note: Erasable pens are not recommended for use on legal or office documents. Do not expose to extreme temperatures (140 degrees Fahrenheit) If pen is exposed to temperature that reaches 140 degrees Fahrenheit, the ink will be colorless when writing.  To restore color, cool to at least 14 degrees Fahrenheit in freezer & ink will write.
