The OEM FriXion Clicker Gel Pen PIL31450 combines the convenience of a retractable design with erasable FriXion ink. This innovative gel pen allows you to erase and rewrite without damaging documents, thanks to its thermosensitive ink formula that disappears with the friction of the latex-free rubber plug eraser. The pen writes smoothly and can be used on the same spot after erasing, making it ideal for everyday writing tasks. However, it is not recommended for signatures or official documents where permanence is required.
