Yamaha Music School Repertoire Book DVD DVDs 1, 2, and 3 have been used a few times. DVD 4 is new and unopened. Used by a child, but the parents handled the operation and insertion/removal, so the child did not touch them. Operation has been confirmed. There is no particular damage, and I think there are no problems with use. As a bonus, I will also include a lesson notebook (unused) and a music notebook. If you don't need them, please let me know in the comments. For those who understand that these are items stored at home, thank you. A set of 4 educational DVDs for children, providing fun learning. - Title: Repertoire Book DVD 1 - Title: Repertoire Book DVD 2 - Title: Repertoire Book DVD 3 - Title: Repertoire Book DVD 4 - Contents: Educational DVD series for children - Quantity: Set of 4 - Disc Condition: Good Thank you for looking.
