This is a set of three Pigeon and Combi teteo baby bottles. The two on the left are glass. Although they are from different manufacturers, they could use the same slim Pigeon nipples. These nipples are also slim, making it easier for babies with weaker sucking strength to latch on. Left: Pigeon, glass, slim nipple, capacity: 120ml Center: Combi, teteo, glass, slim nipple, capacity: 240ml Right: Pigeon, Mother's Milk Real Feeling, plastic, large nipple, capacity: 160ml The center bottle was used at daycare, so there are traces of tape where a name was attached. Used nipples are also available, so please take a look if you're interested.
