Keep your bourbon cold and your Hot Toddy warm with this set of whiskey rocks. Crafted of soapstone, the two cubes chill in the freezer or warm up in the microwave before being placed in a glass of your favorite spirit. The non-porous, odorless and tasteless whiskey stones retain their temperature for about an hour so you can sip leisurely. Due to the natural material, variations in color among the stones are expected. This pair of whiskey rocks makes a thoughtful gift for the cocktail enthusiast.
