Set Contents: 1) Hegen Bottles 150ml - 2 bottles ● Used for about 2 months after purchase in late May for childbirth. 2) Hegen Nipples * Size 0 (SS) - 2 pieces ● Used for about a week after purchasing new. * Size 1 (S) - 3 pieces ● Used for about 2 months after purchasing new. Selling due to changing sizes. Hegen bottles have a one-touch opening and closing mechanism, so the opening/closing parts inevitably get scratched with use. Also, the cap and hood appear slightly yellowed. Please check the condition carefully in the photos (especially photos 11 and 12) and purchase with your understanding. They have been washed, sterilized, and stored, but please wash and sterilize them again before use. Please refrain from purchasing if you are overly concerned about the condition. These are used items and have been stored at home, so please purchase only if you understand this. Returns are not accepted.
