These are super slim 5.2mm with black tray. The industry standard for packing cds. 1/2 the size of the regular cd case.~ Now packaged conveniently in sealed 200 pc boxes. Ideal for home or light commercial use.
The machine grade of these cases means that these cases can be used in high capacity packing machines. There is less recycled plastic and hence a sturdier case all around with stronger tabs.
