This is a set of Pigeon's "Breastfeeding Real Feeling" bottles: 240ml x 4 bottles and 160ml x 2 bottles. It was very convenient to use the different sizes depending on the baby's growth and the time of day. They are made of plastic. ★Nipples are NOT included★ However, if you wish, I can include up to 6 nipples as a bonus. You can choose from L size (5 available), LL size (2 available), and 3L size (4 available), up to a total of 6. All of these have been used and show signs of wear, so please consider them as a bonus. If you would like any, please let me know the desired size and quantity in the comments before purchasing. ※ Purchased in 2022. ※ Please refrain from purchasing if you are sensitive to used items. ※ There are scratches from use.
