The Whiskey Stone Glass Set is the perfect companion for enjoying your whiskey or scotch 'on the rocks'. This set includes 2 lead-free crystal whiskey glasses with a 15 oz (450 ml) capacity each, along with 6 whiskey stones handcrafted from natural soapstone. The stones never melt, ensuring a more flavorful and colder drink without dilution from ice. Simply wash the glasses in the dishwasher (top rack) and hand wash the stones for reuse. The curved base of the glasses provides a comfortable handfeel, making each sip a luxurious experience.
