This is a Yamaha euphonium YEP621s. The current list price is 473,000 yen. I purchased this instrument as a demo from a musical instrument store and have only played it lightly myself. It's an instrument that resonates richly from top to bottom. All slides and pistons move smoothly. The felts are also as clean as new. Ultimately, I have more opportunities to play other instruments, so I'm selling this to someone who will cherish it, as I'm organizing my instruments. A Yamaha 51L mouthpiece is included. There are no cracks in the case handle. The key is not included. The instrument body has minor polishing scratches and dirt from maintenance, but there are no dents and it is very clean as shown in the photos. However, since it has been in someone's possession, please refrain from purchasing if you are looking for a perfect, pristine item. It will be carefully packed with air padding before shipping. I will consider a price reduction within a reasonable range, so please let me know in the comments section.
