Jewel case insert that lets you increase your disc capacity. This “Smart Tray” is a hinged insert for your standard CD/DVD jewel boxes that holds two discs (one on each side). This black insert takes the place of, and is the same size as the standard one-disc back cover insert. Your jewel case can still accept an insert card or tray liner when using a smart tray. Smart trays also allow you to increase the number of discs that can be held in our Pro-Case multi-disc box.
