TDK Life on Record DVD Slim Cases are half the width of standard DVD movie cases, allowing you to store twice as many discs in the same amount of space. The release disc hub firmly holds the disc in place, and enables quick, trouble-free removal when the disc is needed. By simply pushing the hub, you can release the disc without bending it. Shatterproof TDK DVD Slim Cases bend but don't break. Organize and protect your discs with TDK DVD Slim Cases.
