As opposed to traditional ice cubes, the Avanti Wine Pearls do not melt, ensuring your wine 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. The oval shape is perfect for wine or cocktail glasses allowing the Pearls to slide freely throughout the glass whilst at the same time cooling. They are reusable, non-porous, odourless and do not impart flavour. They offer a perfectly chilled drink from the first sip to the last!
