For those of us in the States, I found similar (if not the same) cases here:
http://www.edgewise-media.com/p2~P~DVMR121B%2D100.htmThe measurements appear to be the same, but no mention of brand. Personally, I'd like to see these become the de facto standard for covers of CD games, since it ought to be less work than re-doing the artwork to fit onto a DVD case.
For those who want a visual, they're roughly the size of a Nintendo DS case (within 2mm each side). They're also nearly half as tall as a standard DVD case, which can go a long way towards getting the most out of your shelving.
The price is right as well, $18.59 + shipping for a case of 100. For me (located near seattle), that came to under $25 bucks to my door
