Hi, I'm new to Medicom's 12" figures, I just bought this rider off ebay. The seller claims that this is authentic, I am a little worried that this may be a knock-off or bootleg because the box's back is mostly written in English, not Japanese. And the tape that seals the box is like the kind we use at home, pulled from a tape dispenser so it has the jagged edges, not the usual circle tape...so I wonder if that's brand new and factory sealed. Hope you guys would be able to help identify if this is authentic or not. Thanks very much!
