Made from high quality, thermal shock-resistant borosilicate glass, Lifefactory glass baby bottles are naturally BPA-free, phthalate-free and PVC-free. These bottles have a traditional narrow neck design and are compatible with most breast pumps for direct-to-bottle pumping. A removable silicone sleeve provides cushioning and grip which helps to prevent breaks. Polypropylene cap, ring, and stopper. Stage 1 (0-3m) silicone nipple included with 4 oz size. Dishwasher safe (place plastic components on top rack).
While very durable, our bottles are still glass and are not unbreakable.
Do not overtighten ring, to allow venting and to prevent nipple/valve collapse. Disassemble after use to avoid creating a vacuum seal. The sleeve may be left on for washing, but if you wish to remove it, immerse in warm soapy water for easy removal and wet it slightly before replacing. Not intended for use in the microwave.
