Glacier Rocks 4-Piece Ice Ball Mold and Tumbler Set by Visk
sku# 4510
Each crystal liquor tumbler is sculpted with a circular channel to match the exact proportions of the ice ball made by its accompanying silicone ice mold. Drop the icy sphere into the channel to chill your liquor faster and last longer than coarse cubes. Each set includes two crystal tumblers and two silicone ice molds. Instructions: Fill the hollow silicone ball with water and place in the freezer for at least 4 hours.
