- These colored pencils use frictional heat to disappear surprisingly cleanly.
- The unique "Frixion Ink" disappears when the temperature exceeds a certain level.
- When you rub the area where you have drawn with the special eraser rubber, the frictional heat generated turns the ink colorless.
- This means that there is almost no eraser residue, and since no eraser is used, no eraser shavings are left behind.
- The lead is soft to the touch and produces soft colors.
- The color disappears cleanly when rubbed with the special rubber attached to the back of the pencil.
- Please feel free to contact me if you have any questions.
