⚫︎ChuChu Heat-resistant glass, slim type, 150ml, 4 bottles PPSU, slim type, 240ml, 2 bottles ⚫︎NUK Heat-resistant glass, 125ml, 1 bottle Total: 7 bottles All bottles do not include nipples. One of the yellow parts of the ChuChu 240ml bottle broke, so I used a 150ml bottle as a substitute. They are exactly the same, so there is no problem using any of them.
