Glacier Rocks Ice Ball Mold & Tumbler Set by Viski

Each crystal tumbler is sculpted with a circular channel matched to the exact proportions of the ice ball its silicone mold produces. Drop the sphere in and it rolls in a slow circle at the base of the glass as you sip, cooling the liquor evenly and lasting longer than coarse cubes. Fill the mold, freeze at least four hours, then use the thumb grip to pop the cap and free the ice.

• 4-piece set: 2 lead-free crystal tumblers and 2 silicone ice ball molds
• Each glass accommodates 9 oz comfortably
• Circular channel in the base lets the ice ball roll through the beverage
• Each ice ball measures 4.5 inches around
• Freeze the filled mold at least 4 hours before use

For whiskey, scotch and bourbon drinkers who would rather chill a pour than water it down.
