Thank you for viewing. This is a Plarail N700S pass case. It is an amusement prize. I took it, but I haven't had a chance to use it, so I'm selling it. In my amateur opinion, there are no noticeable stains on the pass case itself, but there is a small black stain on the tag (see image 3). It is new and unused, but please consider this item with the understanding that it has been stored at a private residence.
