Does anybody remember these? They've become few and far between. It always seemed to take a little more effort to get the dvd out. The Schwarzenegger box set used these cases when it came out back in 1999.

My Anaconda Superbit came in one.

They're made by the same company that makes Amaray keepcases (NexPak). You can still buy them, but they're not making the rounds on studio releases very much these days. The multi-disc Alpha cases are still frequently used by the studios, however. Criterion still uses the full-size doubles for a lot of their releases.
