Get a plastic tub with a flat bottom. Cut a piece of insulation foam to fit. Then use a 25mm hole saw to make holes. You can see about 80 will fit in this size tub. I would use a plastic Ice cream tub for the large models. You can find or make a paper box if you like. The tub is about 3$ at Walmart. It took me and three movers about three days to pack a few 100,000 of a friends Miniatures when he moved.I am going to convert every thing to this type of storage before I move. I have no desire to repeat that nightmare.
