Rilney Green Cutting Mat, 12 x 18 in, Semi-Hard Self Healing Rubber Surface,

Product Overview

This 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's
made. When normal pressure is applied to 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. Measure 17.7 x 11.8 Inches (45x30cm)
