I've used pouches like that before (not deerskin). Have a big one that came with some luggage as a shoe bag which we dump sample size product into and take on trips with us. Have an old bank money bag like that, IIRC people used to drop in their coinage and carry in a jacket pocket and such. I prefer soft cases inseatd of hard (like the altiods tins) because they flex a bit so you don't have to jigsaw things into them.
