Store date: post-longbox years
Looks like an integral part of a torture device? Or a particularly insensitive massage tool? Maybe, but No.
After the elimination of the CD longbox, we threw a whole bunch of money at the purchase of hundreds of permanent clear plastic compact disc “keepers” that retained the shape of the longbox, but required no re-fitting of our custom-built storage and display fixtures. This orange thing was the key that opened each of those keepers.
