The 16.5 x 11.7" dark green Self-Healing Cutting Mat from Rotatrim is used by artists, photographers, and students to cut paper or photographs down to size for projects. The 5-layer double-sided mat protects work areas or cutting surfaces from sharp blades, and also protects blades from becoming dull after repeated hits to its surface.

On one side of the mat, one inch grid lines are printed with 1/4" marks along with angle lines at 30, 45, and 60°. The opposite side of the mat has a metric grid with centimeter grid lines, including millimeter marks and the same angle lines. The mat is designed to accommodate an A3 size sheet of paper.
