It's always a pleasure to revisit Chopin and I find this very successful case. The selection is perfect, the brilliant performances and recordings are excellent. Unlike the previous comment, I find that the metal box really brings a plus to the extent it is very nice and close, and the idea of having the CD with cardboard covers equally successful optimizes space and information. I personally would be very impractical in favor of replacing the big plastic boxes, with pretty covers, a booklet and a box like this. Moreover, usually with a plastic case, one is obliged to consult the booklet for details of works. Here, one can refer to the included if desired, and you can look just as good the back cover of each CD, which is very thin and therefore easy to store. More either plastic breakages, more difficult to remove a CD, etc. Very nice Evolution!
