Bought this battery case from Apple Store (with receipt as proof).
Since I've already changed my phone, this case was used for one week only and left redundant.
Very new and clean, no spots at all, as you may see from the pictures! It doesn't look like it's been used.
I take care of my stuff very well, and clean them often. :)
