Retail Price: ¥137,500 YAMAHA product page: https://jp.yamaha.com/products/musical_instruments/winds/trombones/ysl-354/index.html I purchased this a few years ago for club activities, but I only played it a few times due to the effects of the coronavirus pandemic and then stored it away. Please understand that I have not had it maintained. There is a small dent in the third photo, but I don't think it will affect the sound much. I will also include the YAMAHA hard case, the slide oil that came with it at the time of purchase (as shown in the second photo), and a cleaning cloth. I can hand-deliver it if you are in Tokyo. I am considering disposing of it if I don't find a buyer soon, so I will lower the price if you have a desired amount. Please feel free to inquire.
