Keep your cocktail colder. This nifty design is basically an inverted wedge. Whereas most regular ice wedges sit flush against one corner of the glass, this silicone mold creates a negative wedge in the middle of the glass where the liquor sits. Since there’s ice on both sides of the glass, your liquor will keep cool for much longer. Plus, the unique shape is sure to impress fellow liquor connoisseurs at your next cocktail party.
