A type of DVD case used by Warner Home Video and others. Consists of plastic inside, and the cover itself is cardboard.
Case is opened by snapping the plastic side open.
Collectors don't seem to like it. I can see why:
It's clumsy, and cardboard is generally, um, softer than plastic. Judging from consumer opinion, this type of cover is troublesome if you're ordering DVDs via mail - the point of the case is to protect the DVD, but the cardboard isn't too protective.
