SKB Universal Large Bore Trombone Case. I've had this case since 2018, and it's been great. Only selling because l upgraded to a Marcus Bonna. Super tough and durable, and very protective. There's a few scratches on the outside of the case, the handle is not in amazing shape, and it's missing a spot for a TSA lock on the center latch. Retails for $240 from SKB's website brand new.
