Thank you for taking a look (*^^*) This is a Medela nipple shield for sale. I found it very helpful when I had my first child, so I prepared it for my second child as well, but I didn't end up using it, so I'm selling it! I bought it around March of last year. I sterilized it with Milton in preparation for breastfeeding, but I never used it. After sterilization, I dried it and stored the two shields together in the case. There are faint water spot marks from drying, and due to the nature of the product, it tends to attract dust, so I would appreciate it if you could wash and sterilize it before use. Please note that there are no instructions or outer box. I plan to ship via Yu-packet Post. Please feel free to comment if you have any questions (*^^*) Thank you for your consideration!
