It's been a while since I've been on this forum, and the first thing I see is this! Man, I'm glad you guys posted about this. I had no idea this could happen, as the only acrylic cases I have are with AFA graded figures. Based on the comparison pics, I think the AFA cases are a better design. More pricey, but I think they're worth the money until perhaps Oscar comes out with a better solution.
I really feel for those that have had MOC's damaged by a case. I'm pretty damn anal when it comes to handling figures, and I can't even imagine sliding an awesome MOC out of an Oscar case and hearing the card get damaged.
