Flexible silicone allows for easy removal of ice cubes. Free from PVC and phthalates. Simply pour breast milk, yogurt, or puree into the compartments, cover the mold with the lid, and place it in the freezer. To remove the ice cubes, gently twist the mold. Clean before and after each use. It is recommended to wash by hand with hot water and soap, then rinse thoroughly. Do not use aggressive bleaches or sterilization tablets. Sterilize the silicone products in a steam sterilizer or by boiling them in hot water for 2-3 minutes. Also, avoid UV sterilizers as they can shorten the lifespan of the products. Regularly check that the product is still completely intact and replace it if there are any signs of damage. Do not store the item near sharp objects. Use only soft sponges or brushes with soft bristles for cleaning. If the item comes into contact with dishwashing detergent, the material may discolor to white. This is not a toy. Use the item only for its intended purpose and under adult supervision. Store the item in a cool, dry place and avoid direct sunlight. Please follow the guidelines of health organizations regarding the safe collection and storage of breast milk.
