These are brand new quad DVD boxes with a double-sided hinged tray to conserve space. These boxes hold 4 DVDs in the space of one standard (14mm) DVD case! These cases have a full clear wrap-around sleeve (this is where you slide the front paper / artwork into so it shows). From the outside they look like a standard clear single DVD box, but inside the hinged tray allows for 4 discs to be held in a minimum amount of space! This is the perfect space-saving design! Clear is perfect for showcasing double-sided artwork in DVD cases! These cases feature two clips on inside of spine to hold inside paperwork. Each case measures 7.5" x 5.3" x .55" (191mm x 135mm x 14mm)
