This is a set of baby bottles from NUK, Pigeon, and chuchu. I can also sell them individually, so please feel free to consult in the comments. Except for the ones from the Breastfeeding Consultation Room, these were purchased last year and have been hardly used. For hygiene reasons, all nipples have been removed. Please refrain from purchasing if you are overly concerned about cleanliness. If you'd like to try any of them, please do.
