Does anyone know where you could get more of these cases that are in the boxset ? The make of the box's for the region 2 set say ONE-Time on the spine. They need to be the same size of a standard case but can hold 5 discs. I've looked everywhere on the net but cant find any, Ordered some off ebay but they wouldnt fit in the boxset. One of the cases in my boxset is slightly damaged and i would like to replace it.
