This is a set of one Pigeon breastfeeding nipple in size S (round hole) and one in size M (three-cut). *Please note that these cannot be used with the Breastfeeding Realization Slim type bottles. Unopened as shown in the second photo. The product condition is listed as "Like New" because there is no box. The box will not be included to save on shipping costs. If you would like the box, it will be shipped flattened. I will sell this to someone who understands that it has been stored at home. Thank you very much.
