The ink becomes transparent when rubbed. "Frixion Series" refill. It uses a unique "Friction Ink" that disappears when the temperature exceeds a certain level. When you rub the writing with the special rubber eraser, the friction heat generated makes the ink colorless and transparent. It doesn't leave any eraser residue even when rubbed. Because it uses temperature changes to make the ink colorless, it doesn't produce any eraser residue. It can cleanly erase even ink that has seeped into the paper's fibers, leaving virtually no residue. It can be written on and erased any number of times. You can rewrite over the erased section as many times as you like.
