This 'budget' CD book is exaxctly that - BUDGET - it will break unrepairably before it is completely full. That is, the zipper is plastic and is not strong enough to hold together the booklet when filled over 80% to capacity or so. It is an ABSOLUTE waste of money and time, since you will have to just transfer your CD's to a higher quality - and, unfortunately, higher priced - CD book (such as a Case Logic) after this one FALLS APART.Please take this review seriously. There's a reason this is less expensive than the competition - it is of absolutely, frustratingly inferior quality.
