Question: do frixion pens erase with heat?
Answer: Pilot FriXion ink operates by turning clear when exposed to increased temperature due to the friction of the eraser on the page. However, the ink can be erased through any exposure to heat, including warm water, a hot car, or even fire! Pilot FriXion pen ink turns clear at 140°F/60°C and regains its color at 40°F/4°C.
