This is a case for a Marcus Bonna tenor-bass trombone. It shows considerable signs of use. I think I've used it for about 4 years. There are noticeable stains, such as where patches have been removed. The inside of the case is clean. The shoulder straps were quite deteriorated, so it's the case only. How about this for those who are having trouble storing their trombone at home? Please consider. #MarcusBonna #TromboneCase #Trombone
