Good luck getting your money back. That box makes me sad. 
With the way that ebay/paypal works, there's no luck involved.
Buyer makes claim
Seller defends claim
ebay doesn't give a flying fuck about sellers, buyer gets money back
I'm not saying that he doesn't deserve his money back, but just that there's nearly zero reason to worry about buying most anything on ebay anymore. They'll side with the buyer 99% of the time.
