Are there faceplate holders out there?

I'll like to keep my plates in top shape, but can't seem to find a place that has faceplate plastic holders, like the ones that usually came with the NCAA football plates(if you've ever had one). They are like blister plastic types that clamp on the sides. Any leads greatly appreciated.

I think I checked with Imageware once. They were either expensive, like $1.50 each, or you had to buy something like 5,000 of them. I don't remember but I do remember it wasn't a reasonable solution.
