Brand new in box Joovy Boob Glass Bottle with Silicone Sleeve, 5 oz, color of the sleeve is teal, comes in a box. Box has some flaws from storage. Note I am selling just one bottle, not the set of 3. The Boob Glass Bottle with Silicone Sleeve is the most innovative baby bottle on the market today. The nipple design, Clean Flow Vent System, silicone sleeve, and bottle are state-of-the-art and use today's best design and materials. Some old fashioned things just can't be improved upon and the Boob Glass Bottle is a classic example. Glass does not absorb odor, color or taste, so it is an excellent material for baby bottles. The Boob Glass Bottle can withstand a sudden temperature change of 176 /80 Degree C. The silicone sleeve reduces slips and provides an excellent cushion against bumps and drops. Transitioning from breast-to-bottle, bottle-to-breast, or bottle-to-bottle can be frustrating and delicate, but the Boob Bottle's innovation and technology make it a "natural" choice for quick and easy transitions. Available in 5Ounce and 8Ounce sizes. Features: Glass bottle does not absorb odor, color or taste (BPA and PVC free) The 1-piece Clean Flow vent is easy to clean, it prevents leaks, reduces colic and provides a consistent liquid flow Unique nipple design prevents nipple collapse, promotes proper latching and allows for easy breast-to-bottle and bottle-to-breast transitions Silicone sleeve reduces slips and breakings Includes Stage 1 Slow Flow Nipple for 0+ months
