This pack of Derwent Specialist Artist Erasers contains two high performance, non-abrasive erasers. The Technique soft Eraser is a soft textured eraser that can be used to gently lift charcoal and graphite from your paper. The Artist Eraser has a hard texture and is best for use on dense areas of graphite or soft coloured pencil. They both have a strong absorption quality and are non-toxic and latex free.
Good sturdy erasers, though need to take care on erasing on boards in order not to damage the painting surface. Roy Clague (Isle Of Man, United Kingdom) on 7 Apr 2021
