Breast Milk Consultation Room SS size 4 pieces The Breast Milk Consultation Room nipples tend to yellow, so they are all slightly yellowed. Breast Milk-like SS size 1 piece S size 4 pieces (1 of which is new) M size 5 pieces L size 4 pieces (1 of which is new) All items were stored in a dark place after use. There are some minor scratches and scuffs from use, but there are no chips, cracks, or deformations, and they are still in usable condition. The nipples are made of silicone, so they tend to attract dust, but please understand. Please purchase if you understand that these are home-stored, used items. As these are hygiene products, please wash and sterilize them before use. Because my child refused baby bottles, I tried nipples for cleft lip and palate from Pigeon, as well as baby bottles from ChuChu and nipples from NUK, in addition to the breast milk-like ones. I have them listed separately, so if you would like to purchase them together, please let me know in the comments section.
