I purchased this flute about a year ago on Amazon for approximately 10,000 yen. I usually play the saxophone, and I bought this out of interest, but due to my lack of knowledge, I was barely able to produce any sound, so I am putting it up for sale. The condition is generally clean, with some minor dirt and small scratches that are hardly noticeable. I believe it's ready to play immediately, even without maintenance. I am not a flute expert, so I don't know the specifics, but I handle instruments regularly, so I can answer some questions. Thank you.
