I purchased this set here and only used the DVDs. I am offering it at a bargain price because DVD disc 5 is damaged. Worldwide Kids ● DVDs: All 30 volumes ● CDs: All 18 discs (traditional&popular songs1~6)(Chants,Rhymes,and Mother Goose1~6)(Picture Book1~6) ● Parents' Guide: All 6 volumes ● Picture Books: 17 books (7 missing) Everything in the photos is included. DVDs and CDs can apparently be copied, so returns are not accepted. The DVD case has some tears and repairs. To reiterate, only DVD disc 5 is damaged. Since the content is not a continuous story but rather short segments that gradually increase in level, even though DVD disc 5 is damaged, I think you can still use it without much trouble. The picture books have tears and show significant wear on the covers. The contents are readable. I have confirmed that all the DVDs play without problems on my equipment. (Playback on all devices is not guaranteed.) I showed this to my 2-year-old child for about an hour every day, and they started singing along and learning English words!
