Volume 6 is the only unopened item. The other items do not have any noticeable scratches or stains, but the clear cases of the packages have minor scratches, so please refrain from purchasing if you are looking for a completely pristine item. In order to list the items, I played the first 10 minutes of the opened Blu-ray discs of volumes 1-5 on a PS5, and there were no particular video disturbances. Regarding the audio CD included with volume 3, please note that I have no device to play it, so I have not been able to confirm its operation. Price reduction is not possible.
