Pigeon Mother's Milk Real Feeling Nipple for Baby Bottle, Size S, Set of 2 Retail Price: 1400 yen for 2 I purchased these new and used them for about 1 to 6 months. I am selling them because my baby has outgrown them. One of the nipples has a mark that looks like a bite mark, but I think it can still be used without any problems. See image 4. To keep shipping costs down and offer a lower price, I will flatten the nipples when packing them for shipping. See image 3. Please understand that these are used items before purchasing. I am also selling other nipples, and I will offer a discount if you purchase multiple items! Thank you for looking.
