Where to buy the honor box "cardboard stand"

[RikaKazak]

Back when I was a kid I remember these stand up cardboard honor box mint dispensers and can't find where to buy them.  Basically the operator would put mints in these little slots, and when the person took the mint, the back drop said .25.  They could then slide a quarter into where the mint used to be located.

I currently have 32 acrylic mint honor boxes from Sheridan systems out on location, and instead of pulling my "high theft" locations, I wanted to try out one of these types of displays to see if it'd cut down on theft enough to make keeping the high theft accounts worth while.

If you know where to buy them, or even know what they're called (or who made them) I'd be SUPER grateful!!!
