Eraser Derwent battery operated

The Battery Eraser is ideal for creating unusual effects and for experimenting with different drawing techniques. It can of course be used to rub out unwanted marks too! When the eraser is switched on, the spinning action of the eraser lifts pigment from the paper. The precise control offered by the eraser makes it suitable for highlighting and refining marks and amending small areas of work. The operating button is positioned on the top of the eraser which means it is ideal for left and right handed people and is very comfortable to use.
