So simple and so crafty. Say goodbye to nicks and gashes on your work surface when you protect it with our 12" x 18" Self-Healing Cutting Mat. Whether you’re trimming photos and cardstock or slicing a precise diagonal edge, cut lines on this self-healing mat virtually disappear, leaving a smooth, snag-free surface for writing, drawing, or calligraphy. Featuring a grey surface on one side and a black surface on the other, the 1/8" grid is marked in inches on two edges and centimeters on the other two edges. Angled line markings help with diagonal cuts, while the non-slip surface helps hold all your materials in just the right place. Mats are heat resistant up to 140-158°F (60-70?).
