Game box replacement help

I have a few used games, the disks are perfect, but the game cases are in a mess. I was trying to find somewhere that i can buy replacement ones.

I can find the solid green ones easilly, but the clearer green ones that the 360 uses i am having trouble finding. Does anyone know a website where i could order these, or even a store i could find them at?

Look on Ebay for 360 games that are horrible and cheap or look for people just selling the cases.mr_stumpy
