Keep your knives sharper for longer by using a Kussi Flex & Grip Cutting Board. The BPA free, antibacterial, and food-safe grey poly material will not dull knives. The 2mm thick mat is sturdy and durable yet has enough flex to allow easy funneling of chopped food into a bowl or pot. The non-slip grid backing grips surfaces and holds the mats in place during use. Odour resistant and dishwasher safe. Always wash cutting mats with hot soapy water.  Rinse and dry between food preparations.
