Only problem I can see is the OP is claiming its Old, from China and made of Porcelain.
Problem is if it is a fake then it won'tbe old, or from China and maybe not even made from porcelain.
Okay the FBI won't get involved but I would expect a chargeback on the account and a report to Ebay if it turns out to be fake.
It would have been better just to advertise it as "Marble, old looking with Chinese style pictures painted on it" and then there would have been absolutely no comeback.
As it is, the OP is indeed making claims which he doesn't know for sure unless he has had an expert already examine it?
yeah the good old charge back is a bad thing, have been through a charge back before and paypal dont care, it maybe i will take this off and look into it further as i dont fancy spending this money and then 2 months later get a charge back
