Quality of the bag is good. There are quite a few compartments on the inside. And the make and material used feels like it's of premium quality. Only complaint is the material of the piano keys, though it's more of a personal preference than lack of quality. Overall this is a great bag, and it looks and feels like the same exact bag used by Nodame on the live action movie. If ever I meet Juri Ueno in real life, I'd get her autograph written on the piano keys.
