This listing includes nipples for the Pigeon breastfeeding bottle, sizes M, S, and SS. Purchased new in September 2025, they were used by a child for about 3 months. Since breastfeeding was the primary method, the nipples were used infrequently. - Brand: Pigeon - Sizes: 2 x M size, 2 x S size, 1 x SS size - Target age: From 0 months - Intended use: Bottle nipples Although there are no stains, please understand that these are used items. They have been sterilized with Milton. When shipping, the nipples will be flattened in the center. I hope someone can use them.
