Open spindle of 50 black compact Discs. These are intended for the standalone tabletop Hi-Fi  home stereo stack/rack recorders. I do not know if they are compatible with PCs, but these are specific to those special recorders that won't accept PC grade blank discs. These type are becoming scarce and no longer in production. They are going to be harder and harder to find. Please see pictures for cosmetic condition. Will ship carefully packaged by me, thank you.
