【Feature 1】 Transparent writing by temperature change! ☆A new ballpoint pen with "Friction Ink" that makes the ink colorless by temperature change. Since the decoloring temperature is set for "friction ink", the frictional heat generated by rubbing the handwriting with a special rubber at the rear of the body changes the color of the ink to colorless, and you can erase the handwriting. 【Feature 2】 There is no eraser. There is little residue to erase. ☆Unlike writing instruments erased with an eraser, erasing scar does not come out because the ink of the handwriting is made colorless by frictional heat. It is also a feature that there are very few erasures compared to erasures of pencils and mechanical pencils. 【Feature 3】 It can be erased over and over again. Unlike chemical formula such as ink erasing solution, it is possible to repeatedly write at erased parts.
