With stolen pictures and descriptions, one lousy photo maybe taken by the seller, and no real feedback, there's no way I'd advise bidding with that seller. There is NO way anyone can authenticate what she's selling - one Feedback - or a hundred - as a buyer doesn't prove a darned thing.
We AUTHENTICATE here, we don't advise on how to gamble on Ebay. And buying a bag under these circumstances is a very big gamble. Leave it to the experts who know how to file fast and effective SNAD claims if or when the item turns out to be fake.
