Enjoy your whisky or scotch ‘on the rocks’. Chilling stones never melt providing a more flavourful and colder drink without dilution from ice. Each chilling stone is handcrafted from natural soapstone. Use again and again - simply wash after use and place in the freezer for 4 hours. Whisky glasses are handcrafted of lead-free crystal with curved base provides comfortable hand feel. 15 oz (450 ml) capacity each.
