I bought a bunch of plastic storage tubes from a hobby store for around $0.75 each. The small ones hold soprano and alto pieces and the larger ones hold tenor and bar pieces. I cut small some foam cushions that stuff into the lids to protect the mouthpiece tips. The trouble with the ones I have is that they are too narrow to hold a ligature and cap. I have to go to the next size up to get the lig and cap to fit.
