I'm curios how do you identify it as fake? Is there any indication besides the fakt that a steelbook of this design might never have existed?
I Always assumed one can only creat "stickerbooks" with putting foil on the steel.
This one doesn't seem like one. Then again, I'm not a pro
Edit: This auction also caught my Attention:

As far as I'm Aware, the steelbooks that came in the UCE of FFXV were not sealed. (Mine sure as hell weren't)
But there was an issue with People not getting the correct Steels in their CE, so Square issues replacements. Dunno if These were sealed or not.
