A decade and a half ago, I bought a whole bunch of these CD sleeves. I just ran out of 'em today. They're made especially for music CDs. You can see the little slit up top where the "edge" of the jewel case paper goes. Makes for nice perusing in the box. And a hundred of these can fit in a box that only accomodates a few dozen jewel boxes. (In case anyone is wondering, I recycled every one of the jewel cases I discarded; didn't throw away a single one, I don't think.)
Anyway, I'll be darned if I can find these anymore. Every search turns up hundreds, if not thousands, of links (of course). But everything I've found is designed for computer CDs, and just doesn't have the assortment of features I'm after.
I'm open to all suggestions, including "You shouldn't spend your time on earthly pursuits", or "You should downsize your collection", or whatever. Most cool, of course, would be "Oh, I bought a batch of these last week. Just go to cdsleeves.com" (Actually, maybe I should try that. After I post.)
