Blu-ray disc. Stored on a shelf. The outer and inner cases, as well as the booklet, have scratches, stains, and deformation (see photos 5-9, etc. - outer case). Please do not expect much from the outer case due to the scratches, stains, and deformation. Please refrain from purchasing if you are sensitive to scratches or stains. The disc surface is relatively clean, but there may be oversights. Operation has been confirmed. Note: Originally a 5-disc box set, photo 20 contains paper instead of a Blu-ray disc. As this is a used item, please purchase only if you understand this point (that it is not perfect). Box
