I am selling items I received, so I do not know when they were purchased or how often they were used. This is a set of 12 Seiji Aiso lecture DVDs. These are DVD-Rs. The packaging has some scratches from storage. The discs have some minor viewing scratches, but they played without issue in my playback environment, so I've rated the condition as such. Please research the details yourself on the internet, etc. They were stored in a dark place in the condition shown in the photos. Please purchase only if you understand that these are used items that have been handled by someone else. I would appreciate it if you could refrain from requesting any additional information. Everything in the photos is included.
