I had bought a few Riker displays from an online seller specializing in all types of display boxes and cases.
They were pretty expensive. On a small local forum a hunting buddy said that the big online multi- dealer in Florida, had some for inexpensive prices. I bought the same sizes that I had bought from the specialty place to compare.
When I got them they looked exactly the same and for less than half the price.
You can go to a crafts store and get some 1/4 thick polyesther foam in colors and jazz up the displays.
Here is a couple of mine I did up with some items.
Some junk and good jewelry items and some relic items .
