Two kneaded erasers. A newer eraser is on the left, and an older eraser on the right. The older eraser is darker due to the graphite and charcoal dust that has become incorporated into the eraser. The kneaded eraser, also  known as a putty rubber, is a tool for artists. It is usually made of a grey or white pliable material, such as rubber (though it can be found in many different colors, ranging from green, blue, hot pinks and yellow ) and resembles putty or chewing gum. 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 eraser  is used to remove thin details. Kneaded erasers are also useful for making impromptu sculptures to sketch from. Kneaded erasers are mostly used for slightly, but not fully, erasing the content of graphite. It has great plasticity and can be molded and shaped into desired forms for ease of usage   .
