High Flexibility: The silicone ice mold is designed with high flexibility, ensuring it remains intact and undeformed during low-temperature cooling, stretching, and kneading. Food-Grade Material: Our ice molds are made of premium, food-grade silicone, BPA-free and odorless. They can come into direct contact with food and are safe for drinking and cooking. Resistant to low and high temperatures (from -24°C to 230°C), they are suitable for the freezer, refrigerator, dishwasher, and oven, ensuring safety and durability. Stackable and Removable Lid: Designed with removable lids for easy stacking and keeping ice cubes clean. The covered ice trays help prevent evaporation, overfreezing, and contamination. These covered ice trays stack easily and neatly in the freezer without sticking, keeping your freezer clean and organized. Easy to unmold: The flexible silicone material of the mold creates a snug fit, and the smooth interior and bottom walls make removing the cubes a breeze. Simply bend the tray and push the cubes out individually. Easy to clean: The smooth silicone surface makes cleaning easy; you can wash them in the dishwasher or rinse them under running water without damaging them. Please note that only the tray is dishwasher safe, not the lid.
