Due to poor sales, the price has been reduced from 3500 yen to 2500 yen! * Since it still doesn't sell, the price was changed to 2400 yen on August 31st. If you are interested, please feel free to comment! * Immediate purchase without comment is OK. Although the time sale has ended, I will consider price negotiations, so please feel free to negotiate as many times as you like! I am selling this because I am quitting the trombone and no longer need it. It was a good item at the time, purchased for 12,500 yen. I have used it for many years, so I think it's a good purchase for someone who is just starting the trombone or doesn't mind used items. I have washed it quite a bit with water, but it is a hygienic item, so you can wash it as much as you like after it arrives and it will be perfectly usable. The mouthpiece itself is perfectly usable. Please feel free to comment if you are interested. Price negotiation is free, so please comment with the amount you have in mind!
