It was recently reported that�IU's special edition of her 3rd mini-album, "REAL", which is scheduled to be released this coming December 9th, has already sold out for pre-order sales after only a few days. The special edition of "REAL" was a way of expressing IU's gratitude to her fans, and it contains the album, a photo spread, a calendar, and post-its. Both the online and offline pre-order sales began on December 9th, but due to high demand for the hot product, all 5000 units were sold out during the weekend. "Even we were surprised at how fast they got sold. The distributors are currently asking us for more orders, but unfortunately it's not possible to produce additional units for now. Because of the sold out special editions, we will begin regular sales a day earlier than planned," revealed IU's agency. Meanwhile, IU will be making her official comeback through KBS 2TV's Music Bank on December 10th. Source: Newsen
