14mm Black DVD Case consists of one center hub and can hold up to 6 DVD discs. Compared to the 14mm Black DVD Case with 1 tray, it is quite different. Instead of overlapping each other with a slip tray inside, there is only 1 single hub that combines all your media into one. Perfect for travel and combination collections. 14mm Black Plastic Case 1 Center Hub for precision and compressed space 6 discs allowed per each case
