Well, here is what SleeveCity says:
Our cases are industry standard jewel cases with either assembled or unassembled trays included. Unfortunately, we can not determine if we have the same or compare our jewel cases to that of what “Staples” or “Best Buy” would stock because we are unsure as to what brand they may carry for retail purchases.
Is there no other place to buy pro grade 10.4mm CD cases with the black inlay? Anyone at all?
