Let's hope that the panel is really leather. If not, I'll be calling my credit card company to refund my money... that's the beauty of using your credit card to pay for stuff through paypal on fleabay.
However, what you've recommended is very good advice. I'll PM the seller just to be sure.
.... just saw this listing on eBay for a red leather door. Not all leather doors have stitching on the door evidently:
