Add a dose of love and give your drinks a reason to sparkle with the heart and diamond celebration 4-pack of ice molds from Tovolo. Avoid watery drinks by using these large, slow-melting cubes to chill your drink. Large cubes melt slowly to prevent diluting drinks, and ice may last long enough to pour another beverage over it. Secure the lid and flat base to ensure molds stack nicely inside the freezer. Freeze multiple ice molds at once by utilizing the vertical space in your freezer. Flexible silicone lids come off smoothly, so ice comes out of the mold with ease. The sturdy plastic construction, leak-proof design, and water-fill line make this ice tray easy to use for anyone. The durable, food-grade molds are BPA-free and dishwasher-safe for the best possible user experience. Made of BPA-free silicone and nylon. Dishwasher safe.
