Holbein Kneaded Eraser

Holbein's Neri Gomu or Kneaded Rubber is an eraser that does not damage the paper when erasing charcoal or pencils. It can also be a tool for "drawing white" or using it for highlighting rather than "erasing lines" only in a drawing. This can be done by kneading and softening the rubber before use.

It does not wear away and leave behind eraser residue, thus it lasts much longer than other erasers. Kneaded erasers can be shaped by hand for precision erasing, creating highlights, or performing detailing work. They are commonly used to remove light charcoal or graphite marks and in subtractive drawing techniques.
