Includes the main body, the original hard case, and a separately sold water pot. As a bonus, I'll include a new cloth with the musical instrument store's logo. I purchased this used a few years ago. I played it a little bit right after I bought it, but I haven't used it since, so I'd like someone to use it. The slide, pistons, screws, and all other moving parts function without any problems. There are some minor scratches and dirt from use, but there are no major scratches or dents. The blurring in the images is to remove reflections. There are no scratches or dents in those areas. Sold as is, I will wipe everything down before shipping. Hand delivery in the Tokyo metropolitan area is negotiable. From the Yamaha HP: ↓ Neo series. B♭ compensating. Valve system is 4-piston. The bell is yellow brass, 300mm in diameter, the bore size is 15mm (1st-3rd) / 16.8mm (4th), silver-plated finish.
