The OEM Pilot FriXion Clicker Erasable Gel Pens feature a retractable design combined with erasable FriXion ink. This innovative thermosensitive gel ink formula allows you to erase and rewrite without damaging your documents. The rubber plug eraser effectively removes ink without leaving any residue or debris, enabling you to write on the same spot after erasing. Ideal for smooth writing, these pens are not recommended for signatures or official documents where permanence is required.
