8oz/250ml Narrow-Neck "Options" Conversion Kit (1 Cap, 1 Collar, 1 Insert, 1 Reservoir)

Dr. Brown's Options Conversion Kit converts the original Dr. Brown's 8 Ounce bottle into a Dr. Brown's Options 8 Ounce bottle. We recommend using the vent system to experience all the health benefits of our bottle. Some moms and dads find removing the vent a convenient option as their baby's feeding becomes more developed.
