The OEM FriXion Clicker Erasable Gel Pen PIL31452 combines the convenience of a retractable pen with the innovative, erasable FriXion ink. This pen allows you to erase and rewrite repeatedly without damaging your documents, thanks to its thermosensitive gel ink formula that disappears with the friction of the latex-free rubber plug eraser. The pen writes smoothly and is retractable by pressing the clip down. However, it is not recommended for signatures, examination papers, or any official documents where permanence is required, nor for exposure to extreme temperatures.
