The clarity and shine of these standard, polystyrene jewel cases make them a favorite. In terms of clarity, few plastics can match it and no others that are inexpensive enough for disc packaging. Standard CD jewel cases are available pre-assembled or you can purchase your jewel boxes and standard CD trays separately. You can also find chubby jewel cases for holding multiple CDs. Polyline's CD jewel cases are in stock and ready to ship the same day from Chicago or Los Angeles.
