These silicone mats measure 78.7 inches by 15.7 inches with a thickness of 1.3 millimeters, about 30 percent thicker than typical 1 millimeter mats. The size provides a large, stable working area and can be trimmed to fit different countertops or craft spaces. Made from 100% food-grade silicone, the material is BPA-free and free of chemical odors, making it suitable for food preparation and child-friendly activities. The surface is non-stick and easy to knead or roll against, while the underside features a textured, non-slip design to keep the mat in place on a counter. Heat resistance spans from -40°F to 446°F, allowing use under heat sources or to shield surfaces from hot pans. The mat lays flat and resists wrinkling, and its thicker profile offers resilience against bending during use. It also functions as a reusable surface protector, guarding countertops from scratches, spills, and grease. In addition to kitchen tasks, the mats support crafts, DIY projects, and classroom activities, including molding, jewelry casting, painting, or paper crafts. They can be rolled for storage and cleaned with mild soap and water, providing a versatile, reusable workspace for a variety of everyday tasks. Color: White.
