I bought these cases, after having in the past, bought some doubtful quality slimline cases, in bulk. The review cases were much better quality, as you would expect, since they cost more. They closed correctly, after a disk was placed on the holding mechanism in the case. The case does the job, and there is a clear plastic film to hold an inlay if you wish to make one yourself.
My only complaint is that I wish the cases were a little more rugged as they feel a little flimsy when you handle them. On the other hand the case latch and disc latch work fine and none of the cases were worn or broken.
