Pigeon breastfeeding bottle nipples, size SS (2 pieces) and size S (3 pieces). Purchased new in 2025 and used for about 3 months. After each use, they were washed with baby bottle detergent and sterilized with steam. They are yellowed and show signs of use, so I have selected "Used - Has some scratches and stains," but there are no holes and they can be used without any problems. Please understand that these are used items before purchasing. I will flatten the tips for shipping.
