This is a 4-piece set of Yamaha Music School's teaching materials, "Primary ②". The textbook, homework, and primary notebook are unused. However, due to home storage, there are slight folds and wrinkles on the covers of the primary notebook and textbook. (Please refer to photos 2 and 3.) There are no issues with using them for lessons, etc., but please refrain from purchasing if you are concerned. The CD is a used item, as it was given to me by an acquaintance. I have confirmed that there are no playback issues.
