Features of Friction Ball Replacement Refills
Friction Ball Pen Series Features
[Feature 1] Ink becomes transparent with temperature changes! This innovative ballpoint pen is equipped with "Friction Ink," which turns colorless due to temperature changes. The "Friction Ink" has a set color removal temperature, allowing the ink color to change to colorless through the friction heat generated by rubbing the special rubber at the back of the body, enabling you to erase your writing.
[Feature 2] No eraser residue. Minimal leftover marks. Unlike writing instruments that use erasers, this pen uses friction heat to turn the ink colorless, resulting in no eraser residue. Additionally, it leaves very little leftover marks compared to pencil or mechanical pencil erasures.
[Feature 3] Can be written and erased repeatedly. Unlike chemical erasers, you can write over erased areas multiple times.
[Usage] After the ink dries, rubbing the rubber at the back of the barrel will erase the color. *Not suitable for official documents or addressing.
