I do not display my collection, but use small Plano lure boxes. Each one has 5 equal sized compartments that hold all shells up to, and including, the 3-1/2" 10 gauge. I have different boxes for 8s and 4s. I have used these little tackle boxes for 20 years and have never experienced any degradation of my specimens, including rifle and pistol cartridges. They stack neatly and offer excellent protection for my shells.
