The item in the image is a silicone ice cube mold specifically designed for use with 30-40 oz tumbler cups, such as the popular Stanley or Yeti cups. Key Features Unique Shape: It creates three large, hollow cylinder ice rings. These are numbered (1st, 2nd, and 3rd) to indicate the order they should be stacked inside the tumbler, with the smallest ring going at the narrow bottom and the largest at the top.Slow Melting: Because the ice cubes are oversized, they melt much slower than standard cubes, keeping your drink cold for longer without diluting the flavor as quickly.Design: Most versions of this product come as a set that includes the flexible silicone mold, a sealing lid to prevent freezer odors from contaminating the ice, and a storage bin to hold the finished rings.
