When it comes to baby bottles, BPA is decidedly out. Glass is trying for a comeback, but fear of breakage keeps the masses from buying in. New 5 Phases baby bottles combine the best of both worlds with their innovative design: a BPA-free clear, plastic shell with a removable glass insert inside. In the unlikely event that the glass should break, the plastic sleeve holds everything safely inside. Silicone nipples available in 3 flow rates complete the package. SOLD!
