The case is wide enough and tall enough to store plenty of discs (see product description)- no more need for stacks slippery plastic cases or flimsy space-wasting "shelves!" An added feature is that the inside cover also has slots/pockets. I used these to store back-up program discs that I would not expect to use often, but would want to be able to find right away.The outside zipper is not as heavy-weight as, for example, the one on a teenager's school notebook that would be opened and closed multiple times each day, nor does it glide as easily. It's conceivable that this is due to the fact that mine is not yet full. If you intend to use it often, you may end up leaving it unzipped. I like it well enough, however, that I'm considering getting a second one for DVD storage next to my TV.
