Set of 4 baby bottles (160ml), a Milton sterilizing case, a breast pump, and one size S nipple. The baby bottles include 3 glass bottles and 1 plastic bottle. I bought this set to use right after giving birth, but I didn't use the breast pump, although I did sterilize it. Since I was using a mix of formula and breast milk, the numbers on the frequently used bottles are difficult to see. I will pack everything in the case, wrap it in bubble wrap and then in a plastic bag for shipping. I sterilized the items before using them, but please sterilize them yourself before use. Thank you for looking.
