[Erasing with Friction] POINT 1: The ink becomes transparent when rubbed. POINT 2: No eraser residue is produced when rubbed. POINT 3: Can be written and erased repeatedly. [Mechanism of Friction Ink] Friction ink uses special microcapsules that act as the dye. The combination of three components contained in the capsules changes due to friction heat, making the ink transparent. [Note] Do not use on important documents or addresses that must not disappear. - Do not place in direct sunlight or in high-temperature areas. The ink becomes colorless at temperatures above 60°C. - At around -10°C, erased writing may reappear. - Do not use on surfaces other than paper. Depending on the type of paper or characteristics of printed materials, erasing may not be effective. - If the eraser is dirty, it may stain the paper. Clean the eraser before use. - Not suitable for mark sheets.
