Query: Sturdy Case for Your DVD/CD Collection

This is a really sturdy case for your DVD's/CD's. I feel like my movies are really safe in it. The DVD/CD sleeves are high quality and I haven't had any to rip as of yet. My only complaint is that it's a little difficult to open (not the lock, the case.) I particularly like the locking feature.
