Avanti® Whisky Rocks will chill and take the edge off your favourite spirit drink without diluting it. Unlike traditional ice cubes, the Whisky Rocks will not melt, therefore don’t water down and weaken the taste of your drink. They are reusable, non-porous and odourless and do not impart flavour. They offer a perfectly chilled drink from the first sip to the last! To use Whisky Rocks simply store them in a freezer in their velvet pouch. When needed, simply rinse with water before dropping 2 or 3 rocks (depending in desired temperature) into your drink to enjoy. For effective cooling, place then in the freezer 4 hours before use. Wash Whisky Rocks before first use. To clean, rinse with warm water.
