FriXion Clicker Erasable Gel Pens combine the convenience of a retractable with incredible, erasable FriXion ink. Erase & rewrite repeatedly without damaging documents. Thermo-sensitive, gel ink disappears with erasing friction of latex-free, rubber plug eraser on the pen. Erasing leaves no residue or debris. Pen can write on the same spot that has been erased. Retractable gel pen delivers smooth-writing gel ink & is not recommended for signatures, examination papers or official documents where writing needs to remain permanent or for exposure to extreme temperatures. Retract by pressing the clip down.
