Cocktail ice ball tray makes 4 perfect 1.75 inch ice balls to keep your favorite drink cool. Ice balls melt slower than ice cubes, so your drink will stay cold and not become diluted with water. For an added treat, freeze your favorite juice, coffee or drink into ice balls and use them to cool your drinks. Easy release tray is dishwasher safe, leak free and reusable, can be done with spot color imprint or debossed laser engraving. Standard Package include 1 piece easy refill funnel.
