Lorenzo,
Those cases are called Riker mounts and available in all sizes. Here's aplace to buy them:

I've used them for years, I might suggest to jazz up the displays buy some fabric in a neutral color (I like khaki) but can use any colors you like, cut to fit and place on top of the padding, place your badges and close up the mount, looks very professional that way.
