I used two Pigeon Milk Bottle Real Feel bottles for about a year. The NUK bottles and nipples are unused. The used Pigeon nipples are size S. I used these for about 3 months? Please let me know in advance if you don't need them for hygiene reasons, and I won't include them. I'm also including a new Raku-Raku Milk attachment, as I have one extra. (^^)
