This is a textbook for learning Korean. There may be some signs of use, such as on the corners of the book... ! A CD is included, and it has never been opened, so I think it can be used without any problems. *There is writing on about 10 pages. As shown in the photos, there are parts written in ballpoint pen and marker, which cannot be erased. The other pages are unused and I think they are clean, but if you are concerned, please refrain from purchasing. m(._.)m - Title: Latest Challenge!
