[Safe Food Grade Material]: The covered ice cube tray is made of high-quality silicone (bottom) and PP material, and does not contain bisphenol A. Our ice tray is more stable and less prone to water leakage compared to full silicone ice trays. Our covered ice tray is made of food grade soft silicone material at the bottom, which has good flexibility compared to previous hard plastic ice trays. Each flat ice cube compartment is separate, so you just need to open the lid and hold the back, and the ice cubes will pop out directly, which is very easy. Stackable and detachable lid design: Each covered ice tray comes with a practical lid that can be stacked in the refrigerator and save space. It can also prevent ice from absorbing air from other foods in the refrigerator, so you can enjoy clear and clean ice cubes. Easy to use and dishwasher safe: Fill the ice cube tray with water, cover it with a lid, and freeze it into ice cubes. After use, you can clean this covered reusable ice tray by hand or use a dishwasher to clean the ice tray. Air dry the ice tray and stack it in a dry place.
