This case is the best design for holding two CDs. The tray has a fixed spine end with an actual hinge on the part holding the disks to access the second disk. The fixed spine locks the tray insert card in place. There are two inferior designs competing: One looks similar but has trays that use a flexible thin edge as the hinge, which eventually breaks from the flexing. Another has a single piece tray hinged where it attaches the the jewel case, and since the spine end rotates, it tends to snag the spine tab of the tray insert scrunching it or allows it to fall out, especially if you print on plain paper.
