DeAGOSTINI MY MUSIC STUDIO 1〜36 After purchase, I took them out of the cases and stored them in files. Since they are mostly unplayed, the disc surfaces should be in good condition, but I haven't checked them for playback. The jackets (paper parts) have slightly discolored where they were sticking out of the files. These items have been stored at home for a long time. I would appreciate it if you could understand. I took them out of the files for sale and replaced them with new non-woven fabric cases.
