2 Munchkin Latch Bottles. Suction in Bottle for Anti-Colic and Gas Reflux. Size 0-6 month Nipples. Bottles contain 8 ounces. Easy take apart and easy to clean Bottles. These bottles really helped me to transition from breastfeeding to formula feeding, based on the shape of the nipple and the boob shape suction. This are very expensive to purchase in store. (Not shown are 4 5oz Munchkin Latch Bottles). I'm asking $4 a piece for each bottle.
