- Wash Easy: Our silicone ice tray is stackable and has a smooth silicone surface for easy washing. It is recommended to wash before first use. The tray includes a cover and is dishwasher-safe. - Great Temperature Performance: Tolerates -40 to 230 degrees Celsius, suitable for refrigerator and microwave use. Ideal for bars, restaurants, or households to produce spherical ice cubes. Ice cubes can be placed directly into whisky, juice, and beer to chill drinks instantly. - Unique Hexagon Design: 111 honeycomb cubes with lids. It lets you make neat cubes while preventing spills and the freezing of excess water and flavors in your freezer. The tray can be stacked one on top of the other or nested inside each other to save cabinet, refrigerator, or freezer space. - Great Flexibility: Made of silicone, the cubes are flexible and recover quickly after twisting. Eco-friendly and non-stick; it will not stick to ice during freezing and releases cubes more easily.
