Set of 4 Nipples for Baby Bottles (Mother's Touch) - Quantity: Set of 4 - Sizes: SS x 1, S x 2, M x 2 I purchased these before giving birth, but I used other baby bottles (KR-100, 200) after delivery, so I used these less than 10 times each. I believe there are no noticeable scratches or significant deterioration, but please understand that this is based on a personal inspection. The tips will be flattened (see photo 2) and shipped in simple packaging.
