Minimal erased residue. ●Unlike writing instruments that use erasers, it makes the ink of the writing colorless with friction heat, so no eraser residue is produced. ●It is also characterized by having very little erased residue compared to the erased marks of pencils and mechanical pencils. ■Feature 3: Can be written and erased any number of times. ●Unlike chemical formulas such as ink erasing fluid, it is possible to write repeatedly on the erased area. ■How to use After the writing has dried, rub it with the rubber at the back of the barrel to erase the color. *Cannot be used for official documents or addressing envelopes.
