A quirky but useful ice-breaker. Made from pure Swedish marble, you take the cubes from your freezer to use as ice cubes in your drink and wash and re-use time and time again. This very pure stone harbours less bacteria and fewer impurities than ice. Serious whisky drinkers will love them as they chill the drink without diluting, and as they don't melt they keep the drink cold for longer. You can also heat gently in the oven (not microwave) and use in mulled wine. These drinks cubes can be used anywhere the water cannot be trusted, which means an ice cool drink anywhere in the world!
