I bought a set of harmonicas of another brand and tried to fit the set in a waterproof case from a hardware store. They did not fit, so I bought a set of the Lee Oskar cases (kept the key labels) and put the harmonicas in those cases. Perfect fit for a set of G through LF. I wanted to have this set up for camping and travel. Great fit. Might buy some more as the individual cases from some manufacturers are odd shape or large.
