Mine's still in the paper sleeves. All the local places only carries slim CD cases which wouldn't quite fit the cover. I ordered a set of 10 blank standard CD cases, they arrived as 10,000 pieces shards. Still waiting, 3 weeks+ on the replacement, I might have to open dispute because the seller hasn't provided new tracking info and may be trying to waste my time to get past the deadline.
I did look into local Goodwill today, nearly all of the CD cases were scruffed, scratched, and sometimes cracked and not worth the 50 cents each to use.
