The slide moves smoothly, and the pistons have been confirmed to function. I believe there are no issues with playing, but there is considerable wear and tear, with paint peeling, rust, and many scratches. The mouthpiece is not included. You can of course play it, but I think you could also enjoy it as interior decoration for your room. Please purchase only if you understand the current condition. If you have any questions, please feel free to ask. Included: Instrument case (Nikkan) #Nikkan #Nikkan #Melophone
