Be careful if you want to use the case with Bach Stradivarius 42BO. The mouthpipe part of the slide can hit the bell. I got 3-4 dnets and some scratches within a day since the case arrived.Not enough space inside the case for water spray and other accessories. All I can fit are 2 mouthpieces (in oversized space) and polishing cloth.you can use side bag for water spray, lubricants and or polishing clothes, but there is high chance to hit the bottle and break it.
