Haakaa silicone milk bags are an environmentally friendly alternative to traditional disposable milk bags. They are a practical solution for storing, transporting and warming expressed breast milk. They can be used over and over again, helping to reduce the amount of single-use plastic waste. The milk bags can be safely placed in both the fridge and freezer and stored lying down or standing up. Simply fill the bag with breast milk and then close it with the leak-proof stopper. If you want to use the milk, you can simply place the whole bag in a water bath and gently warm the milk. The stopper has a handle which makes it easy to take the bag with you. The volume on the bag is only an approximation. Since the bag is soft, no exact quantity can be given. Made of food grade silicone. Free from BPA, PVC and phthalates. Clean after each use. It is recommended to clean the Haakaa silicone products by hand with hot water and soap. The silicone may turn milky in the dishwasher. Do not use aggressive agents such as sterilizing tablets or bleach. Sterilize Haakaa silicone products after each use, preferably in a steam sterilizer or by boiling them in hot water for 2-3 minutes. Also, do not use UV sterilizers as they shorten the life of the products. Check regularly that the product is still completely intact and replace it if it shows any signs of damage. Do not store the item near sharp objects. Use only soft sponges or brushes with soft bristles for cleaning (hard bristles or sponges can damage the surface of the silicone). If the item comes into contact with dishwashing liquid, the silicone may turn white. This is not a toy. Use only for its intended purpose and under adult supervision. Store in a cool, dry place away from direct sunlight. Use only under adult supervision.
