This Alvin Cutting Mat will protect your tabletop from cuts, compass points, scratches and liquid spills. Ideal for a wide variety of applications in office, school or home. The cutting mat has a semi-hard rubber-like surface which allows the cutter to bite into it, yet the cut will miraculously ""heal"" almost as soon as it is made. When normal pressure is applied with a sharp blade, the cut made in the Cutting Mat's surface will disappear to the point that it cannot be seen with a magnifying glass.
