Two Pigeon slim-type nipples, size S, set of 2. Purchased around the end of September 2025 and used for about 2 weeks. They have become white due to Milton sterilization. I am also selling slim-type baby bottles, so if you purchase them together, I will discount the shipping cost. These are used items, so please purchase only if you understand this. *When shipping, I may press down on the nipple tips to reduce the thickness. Please purchase only if you understand this.
