Here's what's included ⭐︎ Bottles: 100ml, 150ml, 240ml Nipples: 2 newborn size, 2 size S, 1 size M Lids: 2 for 100ml bottles, 1 each for 150ml and 240ml bottles, 1 lid with handle Since my baby refused bottles, these were hardly used. The size S and M bottles and nipples were only used about twice, so please refrain from purchasing if you are concerned about this. They have been sterilized with Milton, but I recommend that you sterilize them again yourself upon arrival for your peace of mind.
