Thank you very much for viewing. Selling due to decluttering. I no longer need it, so I hope it can be useful to someone who does. I believe this was sold by U-Can. CDs: Out of a set of 10, Volumes 1-4 are opened, but the remaining Volumes 5-10 are unopened. The original shipping box is also included, so I am listing this as a "complete set." I believe this would be ideal for a collection. Please consider it.
