This is a Yamaha student model. Recommended for beginners. It has an E mechanism that makes the E (Mi) in the third octave easier to play. Overall, it's in good condition, but there are some minor scratches from use, which I don't think are very noticeable. The case is also in good condition. For this listing, I disassembled the entire instrument, replaced any defective parts, and readjusted it. There are no issues with the sound. You can use it immediately. ◎ We welcome your comments regarding price requests and inquiries. ◎ Even during comments, we will prioritize the person who completes the purchase process first, according to Mercari's rules.
