This is a set of 9 Pigeon Mother's Milk Realization S-size nipples, caps, and hoods. As shown in the photos, 3 sets have the old-style caps and hoods, and 6 sets have the new style. Both types can be used with either the old or new style of baby bottles. The nipples and new-style caps/hoods were all purchased between January and March 2025. The old-style caps and hoods were purchased in December 2021. All of the nipples, which come into direct contact with the baby's mouth, were purchased this year. They have been washed and steam sterilized, but please wash and sterilize them again before use. There are no major scratches or stains, but they have been used, so they are being offered at this price. Please refrain from negotiating a price reduction or separate sales.
