I use to share your nightmare dreams... a long time ago there was a Shure mic that came with it's own little white plastic case with foam in it... and after a few years the foam turned green and into mush that damaged the mic. That's why now I put my mic's in a plastic ziplock bag with a few silica gel packs and put it in the ziplock case that come's with the mic... then put that into another plastic lip-lock and into the foam padded aluminum case's and the case's into the mic safe. I know it's over kill... but, I sleep better and I have a lot mic's and never use them all at the same time, so some are always stored.
