How does the erasable Frixion work?
Frixion ink is a unique, thermo-sensitive ink that reacts to heat. When the ink becomes hot, it goes invisible. When it is cool, the ink comes back. The plastic tip (eraser) on the end of the Frixion pen generates enough heat through friction when rubbed against the surface of the paper. To get the ink to reappear again, place the paper in the freezer for a few minutes. Keep in mind that because the Frixion ink is thermo-sensitive you should not leave documents or pens exposed to heat for a prolonged period of time. Never use Frixion for signing legal documents or cheques.
