The COOL Ice bucket is made from double wall of plastic and is topped off with a silicone lid that comes with an integrated plastic tongs. The wavy silicone mat at the bottom of the bucket provides dual protection: the ice cubes don’t damage the plastic when they are dropped into the bucket, and they sit on top of the mat and not in the water left behind from melted ice. You can remove the ice mat and use the COOL ice bucket for hot liquids too. Use the COOL thermal bucket for soups, cheese dips, or other hot liquids. Both the double wall plastic and the silicone material of the lid and mat give the COOL outstanding insulating qualities.
