Pilot Frixion erasable pens are a line of innovative writing instruments that use thermo-sensitive ink. This unique ink becomes invisible when exposed to heat generated by the rubber eraser tip on the pen. By simply rubbing the eraser tip over the writing, you can effortlessly erase any mistakes or make changes to your work. The ink then reappears when exposed to cold temperatures, allowing you to rewrite over the erased area seamlessly. https://sites.google.com/view/....pilot-frixion-erasab
