Well, in the description he says that some figures are not original. So he kind of adverts the buyers without giving details.
It's always the same problem on ebay. Sellers doesn't give some information they know for sure but they don't give, hoping people to buy without asking. Information that some people (like me) are tired of asking for (original/repro, sound and light working, damaged pieces, etc...)
Not serious (and loyal) at all!!!
