Pigeon Mother's Milk Real SS size (0 months) nipple for baby bottles. 3 pieces, opened and used in July 2025. No box. I bought these before giving birth, but I ended up exclusively breastfeeding, so I only used them a few times to give K2 syrup. I sterilized them after each use. I used them a few times during the month of August. To reduce shipping costs, I will flatten them for shipping. Please purchase only if you understand and accept this.
