◆Features of the Frixion Series ■Feature 1 Handwriting becomes transparent with temperature changes! ●A new ballpoint pen equipped with "Frixion Ink" that makes ink colorless with temperature changes. ●Since "Frixion Ink" has a set decolorization temperature, the ink color changes colorless due to the frictional heat generated by rubbing the handwriting with the special rubber at the rear of the body, and the handwriting can be erased. ■Feature 2 No eraser residue. Less eraser residue. ●Unlike writing instruments that are erased with an eraser, the ink in the handwriting becomes colorless due to frictional heat, so no eraser residue is left. ●Another feature is that there is very little eraser residue compared to erased marks from pencils and mechanical pencils. ■Feature 3 You can write and erase as many times as you want. ●Unlike chemical formulas such as ink eraser fluid, you can write repeatedly on the erased area. ■How to use After the handwriting dries, rub it with the rubber at the rear of the shaft to erase the color. *Cannot be used for certificates or addressing.
