This eraser measures 2-7/16" long x 1" wide x 5/8" deep. It fits into any size hand and allows the artist to remove charcoal, graphite and other artist lead more completely than other erasers on the market. Because of the soft character of the eraser you can push down on paper or board to get into any possible surface texture to remove, soften or blend with less harm to the paper itself. The easer springs back due to its formulation. The shape allows you to use any side for various needs. A must for any artist!
