Space Saving: Each ice cube tray comes with a lid that can be stacked on top of each other to maximize freezer space and keep your ice cubes fresh and odor free. Large ice cubes : Each ice cube tray holds a total of 6 large ice cubes (1.8" x 1.8" x 1.8") for a total of 18. Not only can you fill your ice maker with water, but you can also fill it with cocktails, whiskey, wine, fruit, purees, ice cream, complementary foods, baby food or candles . DURABLE FOOD GRADE SILICONE: The silicone ice cube tray is made of food grade silicone and is a flexible, non-stick and washable ice cube tray. BPA free and FDA approved. Unlike other hard plastic trays, our ice cube trays retain their shape once the ice is removed. Easy release: the ice cube tray has raised sections between each compartment to separate each ice cube instead to stick together, making it easier to remove the ice cubes. Just press lightly on the bottom and our ice cubes pop out instantly! No more struggling with frozen drinks! Microwave and dishwasher safe: large ice cubes can withstand temperatures from -40 to 240C and are safe to use in the refrigerator and microwave. Ideal for storing baby food, DIY candles, baking cakes. (Note: the lid cannot be placed in the dishwasher and oven).
