The case is slightly bigger than I thought (though quite light), but it fits a cup mute, a bubble, a plunger, a (Peter Gane) bucket mute, as well as a trumpet stand in the bell. It comes with a strap which is sufficient, though I did also buy the backpack straps.
The case is very hard ? I can sit on it. I will not be worried about throwing it around and being generally careless.
