Double-sided Self Healing Cutting Mat 8.5 x 12 inches

This medium format double-sided self healing cutting mat is a good size for everyday use on the dining room table or workshop, providing a smooth, flexible yet stable cutting platform that prevents damage to any underlying surface. The tough green top and bottom surfaces are durable enough to hold up to light work with a hobby knife.  While the surface can be cut with a knife, it reforms along the cut so that the surface stays smooth and flat. Marked under the surface layer are half inch grid lines, plus measurements in both inches and millimeters, and radii at 1, 2, 3, 4, 5, 8, and 12 inches. Also labeled on each side of the cutting mat are two protractor markings, one at 10 degree intervals and the other at 15 degree intervals, 0 to 90 degrees.
