Maman nipple guard with a clear plastic case. - Product Name: Maman Nipple Guard - Quantity: 1 - Storage Case: Clear plastic case Thank you for viewing. This is a free-size nipple shield. I used it for about a month after giving birth to my first child two and a half years ago, and have since sterilized and stored it. I am selling it now as I have no plans to use it again. I purchased it at the hospital for about 900 yen. Please sterilize it before use after purchase. The box will be folded, and the case and nipple shield will be placed in a zip-lock bag for shipping.
