Food Grade Material - the baby ice cream tray with lid is made of high quality lfgb certified silicone and PP material, Bpa free, odorless, non-toxic, durable and reusable. Can be in direct contact with food. Nice size - 4 pack silicone baby ice cream tubs of 14 ice cubes each for a total of 56 (each cube has a capacity of 27 ML). Great for home use, baby food, parties, festivals and bars etc. Super easy to remove glaze - the bottom of the dubac glaze is silicone. Unmolding is quick and easy, just gently turn the tray and gently press down on the bottom. Less likely to crack than a hard plastic ice cube tray. Spill-Proof Lid As far as properly sealing the lid, it not only prevents liquid from overflowing before freezing, but also bad smells between food. Overlaps and is not bulky. Easy to use and dishwasher safe fill silicone ice cream with water (do not exceed max line), cover and refrigerate . After use, it can be rinsed under the tap or washed in the dishwasher.
