This Glass Baby Bottle Starter Kit makes a terrific gift for parents or parents-to-be! The handy kit comes packed with essentials for bottle feeding. Included in the set are: 2 - 9 oz glass bottles with stage 2 nipples (3-6 months), 2 - 4 oz glass bottles with stage 1 nipples (0-3 months), 2 extra stage 2 nipples, and 2 solid caps for mess free travel! Due to recent concerns about the use of plastics in baby bottles, Lifefactory has created a glass baby bottle with a modern twist. The bottle is covered with a silicone sleeve, which helps to protect the bottle from breakage and makes it easier to hold on to. The sleeve is free of all plastics and is completely non-toxic. The silicone nipple is latex-free and non-toxic, while the plastic ring, plug and cap contain no polycarbonates and are food grade, FDA approved and recyclable. Available in an assortment of colorful silicone sleeves. Shown here in ocean and sky silicone sleeves. Bisphenol A, phthalate, PVC and polycarbonate-free! Cleaning instructions: Both the bottle and the sleeve can be boiled or put in the dishwasher together. Created in facilities that meet ISO 9000 or 1400 labor practices and tested by the independent laboratories of Bureau Veritas.
