These are nipples for the Pigeon Breastfeeding Realization series. There were two in the package, but I only used one. I'm listing the other one because the age range has passed. The box has been opened, but the inner bag has not been opened. I will ship the item in the box. m(_ _)m #BreastfeedingRealization #Nipple #Pigeon #BabyBottle #Newborn #Milk
