Plastic sleeves for cd's...

Most of my cd’s are in Case Logic ProSleeves. Each one can hold 1 cd on one side with the booklet on the other or two cd’s, one on each side. They work great and don’t harm the surface. Link to what they look like.

ProSleeves

I use, and can certainly recommend DiscSox. I also use them for DVDs. Very high quality, though not cheap:

Since most of my cd's are i jewel cases, any new ones that come in cardboard I put them in jewel cases and cut the cardboard to fit tin the case as well or at lease to show what is in there. A case of jewel cases from Amazon is cheap.

I use the clear plastic pages that came with a DVD storage notebook.  Oh, and I use the notebook as well😁
