5 oz. Orange PopYum bottles, 3-pack (with Stage 1 slow flow nipples). Stores water and powder formula separately until hunger calls. The only bottle designed to make fresh formula with a single hand. Breast milk is stored in the bottle with absolutely no leaks! It's isolated from the nipple and vent (common leak points). Great for day and night feedings. Travel/about-town friendly. Daycare/caretaker approved. Reduces diaper bag clutter. Made of only medical-grade silicone and premium polypropylene. Wide nipple and natural latch for a smooth transition from breast to bottle. Anti-colic vent returns air to the bottle, not the baby’s tummy. Only 5 parts and a wide design save cleaning time (no bottle brush required). BPA, BPS, latex, lead, nitrosamines, PET, phthalates, PVC, and TPE free. 3x 5oz. (150ml). Dimension: 8.5" W x 2.9" D x 6.4" H. Unit weight: 385g.
