Made in Vermont by one of the oldest soapstone workshops in the US, these cubes of honed soapstone are used to chill whisky, vodka and other spirits without watering them down with melting ice. Simply store the "stones" in your freezer until they are good and cold and add them to your glass. Non-porous soapstone is made of silica and will not scratch glass, nor will it change the flavor of the beverage. Infinitely reusable, they only need a rinse of water to clean them. Set of nine.
