I bought 1000 heavy vinyl sleeves. They were expensive and intended for the archive. The vinyl caused the surface of the CD or DVD to stick to the vinyl. Ejecting the disk will destroy it. Then I did something really stupid, I bought polyethylene cases. They don't stick. They REALLY fall apart. The glue used yellows and then crumbles into dust. The sleeve is falling apart, really falling apart. I bought 1000 of these and not cheap. Now I only use cheap CD cases.
