Black SlimLine Double DVD Cases NEATO's Slim DVD Cases are half as thick as our standard DVD cases, allowing you to store twice as many DVDs as you'd fit in the same space using comparable Standard DVD Cases. The disc retainer snaps into the disc hub, securely locking the disc in place to prevent damage to the disc. Simply push on the retainer button to release the disc (retainer's appearance may differ from the photo). A DVD Case Insert can be slipped behind the clear sleeve found on the outside of each case, making its contents easy to identify. Each case measures 5 3/8" wide (135mm) x 7 1/2" tall (190mm) x 1/4" thick (7mm).
