Munchkin's Sterilise Bags allow you to eliminate 99.9% of bacteria from bottles, teats, soothers, teethers, small toys and breast pump accessories when on-the-go. Just fill the bags with small feeding items and water, pop them in the microwave, and you're full steam ahead for a hygienic clean! The set includes six bags and each bag can be used up to 30 times. The bags come with an easy spot to mark after each steam cycle to help you keep track of how many times you have used them. And to keep you safe from burns, each bag contains Cool-Touch grip for easy handling and a tab opening to allow steam to escape. Baby-safe cleaning should always come this naturally and easily.
