I still recommend using zip lock bags for the great all around use. I like them since its easy to see inside the bag and instead of using a fork or spoon to mix up the shisha before smoking you can just move around in the bag and you get the same results.
This Picture is just a sample of a couple bags (the one on the right happens to be Blue Mist, Woot lol
). I actually have a duffel bag with a whole lot more hehe. Anyway the bags are really easy to store no need to find a place for big ol tins or tubs, Plus you can write what flavor it is right on the bag. Heck you can go crazy and get a filing cabinet and file those things
