Putty Eraser - Faber Castell
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. However, they are ill-suited for completely erasing large areas, and may smear or stick if too warm.
Although kneaded erasers do not wear away like other erasers, they can become exhausted and unable to absorb any more graphite or charcoal. In that case a kneaded eraser will actually make marks instead of erasing them.
Different colored erasers can be blended together, creating a larger eraser that is a new, unique color. New kneaded erasers can be stretched and compressed easily, changing their texture and form.
Kneaded erasers are also useful for making impromptu sculptures to sketch from. Kneaded erasers are mostly used for slightly erasing but not fully erasing the content of graphite. It has great plasticity and can be molded and shaped into desired forms for better user experience for best result.
