Translation Results Requested Through Conyac Made Public

As you can see on the image, the item was packed in official cardboard box sent from the manufacturer, and figure inside was wrapped in thin paper, of course there is no sign of being fake on the item itself so I wonder why the customer thought this item was inauthentic. My guess is that the instruction of this item on the box was written in Japanese so maybe that was the reason why the customer thought it was inauthentic. There was only one order requesting refund for this item, but may I hear and investigate why this customer thought it was inauthentic? I hope to restart sales at soonest upon Amazon's acceptance of my claim.
