Whiskey stones are awesome because they give you the cooling effect of ice cubes without any of the melting. Plus, they’re reusable. That way, your best liquors like whiskey, scotch, bourbon, and wine stay undiluted but nicely chilled. You can even add the stainless steel cubes to other beverages. Keep cocktails, mocktails, water, and juice cold, without ice too. The four 1” x 1” metal chilling rocks come in a plain clear plastic case that you can keep safely in the freezer. The whiskey stone gift set is perfect for whiskey drinkers to add to their bar kit.
