The product description for this is incorrect.The package includes 25 stiff DVD Case Inserts, and the LabelWhiz software (and a one page "Quick Guide) - THAT's IT! There are no "core labels," "CD/DVD labels," etc...These sleave inserts will ONLY WORK on Standard Thickness DVD cases, AND those cases must have clear plastic pockets for the "label" to slip into.The sleave inserts are also perforated at the corners of the spine. So, they will eventually break off the spine. If they were simply prefolded or impressed it would last longer, but the perforation lines weaken the thick paper stock and will allow the spine to tear off.
