Medela nipples 24mm & Pigeon nipples M, 13mm to 16mm. Set of 4 pieces and 2 cases. If you want to buy them separately, please comment. The Pigeon nipples are unused. I only opened them twice, when I bought them and when I took the photos. They may look dirty, but it's due to light reflection. The Medela nipples were used only a few times. (I found it more convenient to use a breast pump.) Purchased in August 2025. Both have been sterilized, and I believe there are no stains. Please understand that this is a personal inspection. I think they are still in good condition, so please consider them. The original price was about 3000 yen for both.
