I purchased this and used it until the milk ran out. It was only used by one person. Regarding the condition of the items: Pigeon baby bottles (large and small), bottle type, there is dirt inside. I washed them but it wouldn't come off. Please consider this if you can remove it or don't mind. The "Chu Chu" bottle type is relatively clean. The Pigeon plastic ones also have some dirt, but it was not noticeable to me. Also, I discarded all the nipples, so please purchase new ones. Additionally, the sterilizing case also has dirt. I will wipe down the entire item before sending, but please thoroughly wash and sterilize it upon arrival. If there are any other oversights, I apologize. These are home-stored, used items, so please refrain from purchasing if you are concerned. Thank you very much ☆
