Thank you for viewing. I am selling these because my child has outgrown them. [Used] Pigeon Breastfeeding Real S size (approx. 1 month old) 4 pieces Pigeon Slim Type S size (0 months old) 2 pieces ChuChu Baby 1 piece Combi Tetéo M size 1 piece The Pigeon nipples were each used for 2 months, and the ChuChu Baby and Combi nipples were each used once. They have been sterilized and stored. I will ship them without the boxes, and will slightly flatten them for shipping.
