This Protec case has proved to be a safe way to carry my instruments. And in fact has proved to be even more versatile than I'd hoped for when I originally bought it.
It has safely carried my long model Bach Strad Bb cornet, but has also on different occasions proved a safe home for my Schilke C cornet and my Yamaha Custom C rotary trumpet which was a real bonus. There's a pocket on the outside for mouthpieces/oil/extra tuning crooks (in the case of the rotary trumpet).
All in all this case has proved to be a safe, lightweight, protective and inexpensive way to carry my instruments.
