Query: Good price. Thin, but that's good.

These are basic CD/DVD envelopes with a clear window. The tyvek (rip-resistant material) is thin, but that is desirable for storage space. Placing CD's in these envelopes gives you about a 5:1 storage ratio over standard CD boxes. The edgewise fit is just right, as some other envelopes do not fit in my snap case.I bought these for archiving CD's in a snap together box. I am ripping to FLACs a few at a time, and I found that by folding in the flap when I am done, I know that I have done and what I have not yet done. I am glad that I did not settle for paper.
