All items are official. They are not from a Korean wave shop. The back of the trading card is shown in the second image. Immediate purchase is available. Same-day shipping is available (business buyers are welcome to purchase without comment). No price reduction. The price will be increased if there are more likes. I am reluctant to sell this item, so I will remove the listing if there are no buyers. I will reinforce with thick paper, cardboard, etc., and take waterproof measures before shipping. Please feel free to comment if you have any questions. Please purchase only if you understand initial defects, etc. Tracking is available for an additional 200 yen (Click Post), so please comment if you wish.
