This is a lesson bag with a musical note pattern. The material is polyester. Size: Approximately 28cm (height) x 36cm (width) Measurements are taken at home, so some error is included. It will be shipped folded in half loosely with cushioning material. It is new and unused, and has not been taken out of the bag, but it has been stored at home, so I would appreciate it if you would consider purchasing it if you understand this.
