The Hatber kneaded eraser is a specialized eraser for drawing. Made of synthetic soft rubber, it has properties similar to modeling clay: it can easily be shaped into any convenient form for erasing. The kneaded eraser is very gentle on... paper surfaces. When erasing, a static method of erasing should be used: it absorbs graphite particles and does not leave debris. Suitable for drawing with charcoal, graphite, pastel, and other artistic supplies. It helps achieve beautiful light and shadow effects and creates soft tonal transitions.
