As opposed to traditional ice cubes, the Avanti Stainless Steel Ice Golf Balls 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 Golf Balls, simply store them in a freezer in their velvet pouch. When needed, simply rinse with water before gently placing into your drink with the tongs. For effective cooling, place balls in the freezer 4 hours before use. Hand wash only. Wash before first use and allow to dry. To clean, rinse with warm water.
