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. Please note that SmartraysDO NOT have any silkscreened “2 Discs” logo.
