Koh-i-Noor Kneaded Eraser (Soft)
The kneaded eraser, also known as a putty rubber, is a tool for artists. It functions by absorbing and “picking up” graphite and charcoal particles, in addition to carbon and pastel marks. It does not wear away nor 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.
