Glass Babybowls provide a healthy and easy way to store your baby’s meals. But why choose glass storage containers? Glass is the ideal material for storing food. This natural material is environmentally-friendly, neutral and durable. Glass Babybowls preserve the taste of food for longer. Whenever you have made purée or compote for your child, you naturally want the best option to store and preserve it. These storage containers have a screw-cap lid with a hermetic silicone seal. They have graduations (in ml and in oz) and a rewritable surface on the lid, where you can simply note the stored recipe and the date it was created. Babybowls are stackable, meaning they can be easily stored in your cupboards, fridge or freezer. To reheat their contents, use a bain marie system rather than a microwave (defrosting function) or a bottle warmer (or any other appliance that heats with steam) when the Babybowls come out of the fridge or freezer. Sudden changes in temperature can cause glass to crack. To avoid this, make sure you heat the Glass Babybowls carefully. The contents should be at room temperature before warming. They are practical, dishwasher-safe and can be sterilized. These small storage containers are extremely durable. They do not stain when they come into contact with food (such as carrot or tomato) and are recyclable. Our advice for use : - Always remember to remove the lid when heating. - To prevent the jar from bursting, do not fill the Babybowls to the brim before putting it in the freezer. - When defrosting, allow the jar to defrost in the refrigerator (not at room temperature) before heating.
