This is the revised edition of "Dekiru Korean I [Intermediate]". CD BOOK (with CD). I solved the problems once on the pages near the middle, but they have all been erased. Currently, there are no markings, and I think it's in good condition overall. There are no major stains or tears on the cover or inside, but please understand that this is a used item before purchasing. You can use it without any problems for studying. Please check the condition in the photos.
