If you are or know a whisky-lover, these sophisticated whisky stones are a must-have! The stones are the solution to ice cubes melting and watering down your drink, and the natural properties of the stones allow them to conserve either heat or cold for a long time. Simply cool them in the freezer or heat them in the oven and they’re ready for use! The set makes a great gift for all wine connoisseurs, bartenders and whiskey-lovers.
