This is a CD book released at the time of debut in Korea. It's a cute design, like a book or a diary, and it comes with a CD. I cherished it. I think it's rare. The badges are official merchandise or extras that came with the CD. I went to Korea each time to collect them. I also kept the calendar (I think it was a calendar) that came as an extra, and it's still in good condition. I've taken good care of them, but please understand that these are amateur-owned items that have been stored at home for a long time.
