On Ebay, I have seen several Limited Edition Deck Boxes. My brother bought one originally, and it turns that they are American, and not Japanese. They also have the 5D's logo, and they are silver on the outside as well. I have not found these sold in retail stores, or sold by vendors in tournaments. According to my brother, it is believed that they are only offered to the top four duelists in a regional event. I would like to know more about how these Limited Edition Deck Boxes are available. Any information would be appreciated.
