The Hatber kneaded eraser is a specialized eraser for drawing. Made from 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 gentle erasing method should be used: it absorbs graphite particles and leaves no residue. It is suitable for drawing with charcoal, graphite, pastels, and other art supplies. It helps achieve very beautiful effects of light and shadow, and create soft tonal transitions.
