This is a NUK baby bottle. I used it once for my daughter, but it didn't suit her, so I haven't used it since. After use, I sterilized it with Milton and stored it at home. There is no outer box. The included nipple is size S. It has a little bit of wear, but there are no noticeable stains or damage. Please purchase only if you understand that this is a used item and you don't mind the small details.
