I bought EXO's February Miracle album 12 on Taobao. It says that it is signed by 12, and the price is 168 yuan. He said that the signature was absolutely guaranteed to be true. Excuse me.
Really? It depends on the store. Some shopkeepers say it's true, and some are fake. When the last XOXO was sold, there was another store that sold 168 and sent posters. Before buying, ask him if there is any basis and why he signed it himself. Besides, you can find their signatures online to check whether they are true.
