The Munchkin Latch Steriliser Bags provide a convenient and effective way to sterilize baby items using a microwave. These bags are designed to safely and quickly eliminate harmful bacteria and germs from bottles, nipples, pacifiers, and other small baby accessories. The key active ingredient in these bags is steam, which is generated when water is added and the bags are microwaved. The steam penetrates into the items inside the bag, effectively sterilizing them. This process ensures that your baby's items are clean and safe for use. The bags are easy to use and perfect for busy parents looking for a hassle-free sterilization solution. The texture of the bags is durable and heat-resistant, ensuring safe handling during and after the sterilization process.
