As opposed to traditional ice cubes, the Avanti® Stainless Steel Dice Ice Cubes do not melt, ensuring your drink stays chilled without diluting or compromising the flavour. Made from high grade stainless steel with food safe gel on the inside that remains frozen for up to an hour. They are reusable, non-porous, odourless and do not impart flavour. They offer a perfectly chilled drink from the first sip to the last! To use the Ice Cubes simply store them in a freezer in their velvet pouch. When needed, simply rinse with water before gently placing 2 or 3 cubes (depending on desired temperature) into your drink to enjoy. For effective cooling, place cubes in the freezer 4 hours before use. Wash before first use and allow to dry. To clean, rinse with warm water.
