Now you can enjoy a whisky on the rocks without the rocks turning into puddles. Based on an old Scandinavian tradition, these stones have been cut from granite which provides natural cooling properties. These non-porous granite cubes keep your drinks cool without watering them down, prolonging appreciation of the nuanced flavours of fine spirits like scotch whisky or single malt. Simply wash, place in your freezer for a few hours and they are ready for you to pop in your drink without diluting your bourbon, whisky and rye. They are odourless. Perfect gift idea for a whisky connoisseur.
