Thank you for viewing. I am selling these because I have no use for them as I didn't use baby bottles. *This is only one of the two-piece sets in all three boxes. As a bonus, I will include a granular disinfectant. New, unused Pigeon Mother's Milk Realization (Breastfeeding Simulation) Nipple for baby bottle Sizes S, M, L Total of 3 boxes set (1 nipple each) Not sold separately *To reduce shipping costs, I will open the boxes and flatten them with the nipples for packaging. Please refrain from purchasing if you are sensitive to this.
