A handsome leather binder and quality non-acid based sleeves make this an excellent storage for DVDs or CDs for library storage archives
Upon doing resarch, these were a very well made prodcut using acid free storage sleeves and extra 8 sheets could be purchased separately to add up to near 80 DVD or CDs in one conveniently "book binder style storage. If you do go with the extra 8 sleeves, and fill each side of them, along with the initial set of sleeves, this book will be slightly overflowing outward just a tad bit. I had a customer with 73 masters of DVDs, and thus the original 48 storage was needing to be expanded. No trouble at all. So I have taken these to the 80 disc limit. Best to buy two of these and not use the extra expandable full 80. Maybe max it out around three or four extras to keep the book even without bulging out in a full 80 version. CDs are a bit thinner, so 80 is ok. But 80 DVDs make it buldge out just a bit. These binders can handle the load, and the inserts are nice as to how the discs fit. A really good and well made outside bider too! Handome leather. Like the black the best!
