Sure. Just so happened to have a couple left after switching my games to DiscSox sleeves.
Original case on the left vs CaseTopia case on the right.
Original case was from game purchased on Amazon this past Christmas and literally just now unwrapped to take the pictures.
CaseTopia case was purchased about a year and a half or so ago and been sitting on a shelf since.

Another pic. Original case on the bottom vs CaseTopia case on the top...

Taking a real close look, the replacement cases might be a tad more opaque in nature, but once you have a cover in there, you really can't even tell.
I can attest that the plastic used is the same top notch quality as the original case. Not one of those thin, cheap, easily warped crap you get with a lot of replacement DVD and BluRay cases. Of course, do keep in mind that the last batch I ordered was a while ago. Gonna be hard to find real good PS3 game cases anywhere anymore as they were pretty much a one off (ie not DVD and not BluRay size) and just not in demand enough anymore for manufacturers to make a whole lot of them still. Personally, I've been very pleased with any of the cases (both game and DVD) I've purchased from Casetopia over the years. At one point I literally had my entire DVD collection housed in them.
