> It’s important to keep in mind that Pilot FriXion ink will “erase” with any heat, so we don’t recommend storing your notebooks on top of a radiator or in cars during the summer. Additionally, don’t use FriXion ink to take tests or write on important documents. If your writing disappears inadvertently, you may be able to get it to reappear by placing the paper in a freezer that reaches below 14°F, or -10°C.
