The standard CD Jewel case is the most common and affordable CD packaging available. It is a 3 piece construction with a removable tray. The front of the standard CD jewel case can hold a booklet of up to 32 pages. The back of the jewel case normally holds card, printed one side, with two spines. The card may be printed on both sides if a clear tray is used. As seen in many music stores, the jewel case may be cellowrapped to protect it from marking as well as protecting the inside content.
