I rarely had the chance to use this after purchasing it, so I've only used it once or twice. There are no noticeable scratches or stains, and it's in overall clean condition. The pistons and slides function without any problems, and I've confirmed that it produces sound. The accessories (case, mouthpiece, etc.) are all included, so you can use it right away. I will carefully pack and ship it. Instant purchase is OK / Feel free to negotiate the price.
