The Kasai Konro Grill Heat Mat will protect any level, stable surface a Kasai Konro Grill has been stood on. Using charcoal instead of wood to cook on creates a much greater heat due to it's much higher energy content so the coals become extremely hot leading leading Kasai to create the 100% natural Kasai Konro Grill Heat Mat to protect the surface. It will also make a great place to put utensils or ingredients onto to create less mess and clean up on other surfaces.
