@rugger: I thought the paper / disc contact would damage them as well. I'm extra careful when I remove the media hehe.
@DJMind: Stacking them on top of each other is that bad? Does it scratch the media?
You see, I originally bought a 100-pack of these for mainly because they were cheap ($4) and I needed a really inexpensive way to store some of my burnt discs; i.e. not a binder. You guys know anywhere online that sells jewel cases or slim jewel cases or anything better than cd sleeves for cheap?
