Viski Glacier Rocks Hexagonal Basalt Whiskey Stones, Whiskey Rocks Set of 4

These are not supposed to be as cold as ice, nor is scotch supposed to be that cold either. These do a great job cooling scotch without watering it down. My husband uses them with 4 when he is having a glass to himself or splits it between two glasses (two in each glass) when he is having a glass with a friend. I almost bought him the soap stones until I realized they left sediment in the glass every time you used them (gross). These are nice because the still look cool without leaving sediment!!
