Question: how do frixion pens work?
Answer: Our FriXion products' ink “erases” due to PILOT's exclusive thermo-sensitive ink technology. When you want to make corrections on your page, simply turn around your FriXion pen and rub with the FriXion eraser tip as if using a regular pencil eraser. While rubbing, the ink heats up to over 60°C and becomes invisible.
