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