Break-Resistant: Our glass cutting board has polished edges that won't hurt your hands. The tempered glass is designed for safety. Even when it's impacted with enough force to break, it will break up into tiny particles rather than sharp shards, so there is no need to worry about being hurt by the debris. Non-Slip and Heat Resistant: The rubber feet keep it from slipping on the countertop. Can not only be used for preparing dishes, but also soup pots, hot pans or baking trays can be placed on glass cutting mat. It s a perfect countertop heat protector.
