The ones you can get on eBay aren’t bad. They aren’t really sturdy and don’t block UV light. It’s really just good as a dust cover and maybe to protect against indenting on the snaplock AES cases. The price is right though, and I need to order a few myself. The best protector/case made for AES games would be the Kaiser cases, but the website domain is sadly expired and I’m not sure if they’re being produced anymore. I’ve got one of them, and it’s awesome. Thick custom 99.9% UV blocking acrylic as well as a silica gel pouch for absorbing moisture inside of the case. They were really expensive though, $100 after shipping per case. They were made in and shipped from Japan. If you just want dust protection and to avoid minor shelf wear go with the eBay protectors. They’ll do the job for that.
