You can erase your mark completely or use it to just lighten an area. It will lift colour from coloured pencil drawings as well. It is very lightweight – the 2 AAA batteries are most of the weight. You hold it like a pen and control it by either keeping it still or moving it around and by adjusting the pressure you use. It doesn’t take up much room in your toolbox being only about 4 inches long. The translucent plastic body comes in a variety of colours (we send out the colours at random).

You can end up with a fair amount of rubbery bits on the drawing and a dusting brush is helpful to brush it off without smearing anything.

The electric eraser is inexpensive at just £2.50. Many artists keep one in their tool box and one on their desk. It comes with 6 tips and a pack of 30 refill tips is available for just .95

These are really popular, I like mine, and I have heard others say that once you try one you won’t know how you lived without it.
