I can, however, confirm the experience of some the other reviewers. I purchased two 25-packs... and in each there was one damaged case. One had a 2-inch long crack in it's face, but was still perfectly usable. The second had a broken hinge which would have made the case DOA but I was able to repair it with some Duco cement. My feeling is that they are inexpensive enough so that a 4% damage rate is acceptable. (By the way, the package comes enclosed in a cardboard sleeve and shrink-wrapped, so if you were to purchase these in a brick-and-mortar retail store, you couldn't inspect them first as one reviewer has suggested.)
One other fact about Slim Jewel Cases bears mentioning. They don't have spine labels (the label on the edge of the case). You either have to shuffle through them when you're looking for a particular CD, or do what I do and make your own spine label from a stick-on label cut to size with an Exacto knife and a straight edge. That way, you can store twice as many CDs in a regular CD storage rack.
Buying your CDs in spindles and protecting them with these cases allows you to conserve both funds and space! What's not to love?
