pinstruments PBONE1P pBone/Purple Plastic B♭ Tenor Trombone Brand: - I bought this for practice, but I'm selling it because I no longer use it. It has been cleaned, but there may be some areas where grease stains haven't been completely removed. Please understand that this is a used item, so there may be some scratches and dirt. The slide action is a bit sluggish. You can still play it, but please use grease or oil to improve the slide's smoothness before use. The inside of the case has deteriorated, so there may be some debris attached. No instruction manual included.
