Stone Ice-Cubes
Now you can surprise your friends – use special cubes made of granite instead of boring ice-cubes. A set of 8 cubes with a special carrying bag coasts about $20. Whisky Stones operate exactly like an ice-cube – you freeze it in fridge and later, after a few hours, stones cool down your extravagant drinks. Water from ice will never ever again dilute your drink!
