Thank you for viewing. I found this while organizing my parents' house. It appears to be a product offered by U-Can in the Life & Culture field, available through installment payments. Out of the eight-volume set, volumes 1, 4, and 7 are opened, but the others are unopened. *Please note that this product is either new and stored at home or a used item.
