I'm selling these books because I bought them to study Korean but never used them and they've just been sitting at home. Book 1: Shin Goukaku Dekiru Kankokugo Nouryoku Shiken TOPIK 1 Essential Vocabulary Book 2: Shin Goukaku Dekiru Kankokugo Nouryoku Shiken TOPIK 1 Exam Practice - CD is unopened I checked and didn't find any writing or stains, but since I'm not a professional, there might be small stains or writing. Please consider purchasing if you understand that these are used items. Red sheet included. Thank you for looking.
