These jewel cases come with black Smartrays instead of standard trays, allowing them to hold two CDs in a single case. The tray is hinged along the spine and can be flipped up to reveal a second hub on the reverse side. These cases are compatible with all booklets and inserts made from standard jewel cases, and are made in the USA to the highest quality standards. Case-quantity orders are shipped double-boxed with foam pads and air cells for maximum protection. Please not that Smartrays do not have any silkscreened "2 Discs" logo at this time.
