Hard plastic cases for game boxes?

I've seen lots of thin plastic boxes/sleeves lately, but does anyone know of a source that produces something sturdier?

I'm thinking of something clear, perhaps about 1/8th of an inch thick.
:shrug:

 

Alpha Security's AVM406B ("Memory Card Box") will fit most kinds of console game boxes other than Japanese N64. There are a bunch on eBay right now, in fact. Getting the opener is harder because you could also use them to rob Best Buy - I eventually found one though.
Similarly there's also the AVM211GB which fits Gameboy/GBA games.

 

Universal Game Cases, sold in bulk for cheap. I still have a ton laying around at home.

 

these?

if so, I'm really after something more like the previous post, a sturdy, clear plastic container, that would hold/display a boxed game. Perhaps rather like some other genres like baseball cards (not the best example).:banghead:

 

Now those are just cool ! And a great combo to use with covers from thecoverproject.com

Btw, I understand what you say have no clue as where you could get those
