Pigeon Nipple for Breastfeeding Consultation Bottles. Suitable for newborns, it's designed to minimize nipple confusion, making it easier to combine breastfeeding and bottle-feeding. I used it for my low-weight baby, but I stopped using it when I switched to exclusive breastfeeding. It has been washed, sterilized, and stored. I believe there are no noticeable stains. If you need it, I can also include the cap parts, so please comment if you would like them. If there is no comment, I will ship only the nipple. - Material: Silicone - Type: Nipple for baby bottles - Size: SS The box is not included. Shipping via Yu-packet Post Mini. Please refrain from purchasing if you are concerned, as it is not unused.
