发明名称 Corner sanding sponge
摘要 A hand held corner sanding sponge includes a backing layer of an open-celled foam material having first and second major surfaces that meet at a right angle and third and fourth major surfaces that meet at a right angle. The cross-sectional dimension between the intersection of the first and second major surfaces from the intersection of the third and fourth major surfaces is about 4 inches to about 6 inches. First and second side surfaces are located between the first and second major surface and the third and fourth major surfaces forming a generally hexagonal shape. The cross-sectional dimension between the first and second side surfaces is about 3 inches to about 4 inches. A layer of flexible adhesive is adhered to at least the first and second major surfaces of the backing layer. A layer of abrasive particles is adhered to the major surfaces by the flexible adhesive.
