It's the same height and width of a standard jewel case, but only 5.2 mm thick for high clarity, light weight, maximum storage. Our durable Ultraslim features a crystal clear front cover, clear hinges, and a one piece base construction. You cannot use a back tray card. White and black bases are opaque and the clear color features a frosted or translucent base. White base is shown below.
