Thank you for viewing. ・I was collecting these new on Amazon, but after reading partway through volume 1, I kept them stored. I stored them on a bookshelf away from sunlight, so I think the items themselves are in good condition. As you can see in photo 2, there is no sun damage to the books. All volumes 1-21 have plastic book covers. Please refrain from purchasing if you are sensitive to items stored by an amateur. If you have any other questions, please ask in the comments before purchasing.
