With the AdirOffice Cutting Mats come the bonus feature of a different color on each side of the mat - one side is black, the other, green. Not only is this like getting two mats in one, but these two colors are non-glare and easy on the eyes. • Closes immediately after cutting. • 3-ply design with self-healing surface and hard core making it usable on both sides. • Extremely durable, 3 mm thickness. • Non-slip for added safety on work tables. • Calibrated grid lines for easy cutting references. When these mats are not being used for cutting, they make a perfect surface for drawing or writing, thanks to the resilient texture of the 3-ply construction. AdirOffice Cutting Mats are the ideal choice for artists, designers, photographers, illustrators, calligraphers, scrapbookers and hobbyists. Self-Healing Surface: Yes; Surface Format: 1" Grid with Guide Angles; Color(s): Green/Black; Color Family: Multicolor.
