Thank you for viewing! This is Kiku-tan Korean 【Beginner】. I opened it once but haven't used it since, so there are no markings, and the contents are clean. Also, it comes with a red sheet and a CD. As you can see in the 6th image, the book is slightly warped, but I think it won't be a problem for use. Only those who are okay with this, please purchase. Thank you!
