This is a set of four Pigeon Mother's Milk Real Bottle 240ml (plastic) bottles. Used by my older and younger children. The nipples are size L and are still attached. I used these for outings and at home, so they are relatively clean and still usable, but please discard them if you don't need them. I am also selling them as a set with the case and other accessories, so please consider those as well. Pigeon
