The DVD looks like a chinese version perhaps..if not, it's fake.
and the CDs are coming directly from Japan is says, so they shouldn't be fake.

EDIT: all in all, i suggest don't buy anything from Ebay unless you can SEE that is says avex trax on them. [i bought 2 CD bootlegs, and have seen MANY, if not DOZENS of DVD bootlegs ]
If you are concerned and really want that item, and they sell cheaper than yesasia, i suggest you message the person who put the product up for sale.
