This is a tuba set I purchased for my club activities two years ago. I quit soon after for various reasons, so the mouthpiece has only been used a few times. However, it has been left unused for a long time, and there appears to be some rust-like stains (?). I'd like to clean it, but I don't have much knowledge, so I will ship it as is. The metronome I bought at the same time is broken and cannot be listed, but these items are essential sets for club activities, so if you are starting to play the tuba in the brass band club at the beginning of the school year, please consider purchasing them. Price negotiations are welcome. If you have any questions, please feel free to comment, although I can only answer to the best of my ability.
