Ring in cocktail hour with our loop-shaped ice molds. The set's two black silicone molds freeze perfectly round and thick ice rings, adding a fun touch to beverages. Due to their size and substance, the ice loops melt more slowly than traditional cubes to keep drinks from diluting too quickly. To make the ice cubes, snap lid and base together, and fill from top hole with warm water until it reaches the smaller overflow hole, being careful not to overfill. Once the ice is frozen, slowly peel the top mold off, and push the ice up from the base to release.
