Instant purchase is OK! "Solo Leveling" Volumes 1-4 A set of 4 books. There are no noticeable stains, and overall they are clean and do not hinder reading. However, this is a visual inspection by a non-professional, and I have not checked every page thoroughly, so there may be minor oversights. The description of the condition is based on the seller's subjective opinion, and there may be individual differences in how people perceive things such as scratches on the cover, stains, sun damage, minor folds on the edges, damage caused by storage, and aging. If you are concerned about minor details, I will respond by adding images if you ask questions in advance. Please understand and acknowledge that these are used items before considering a purchase. Shipping will be done using the cheapest method of anonymous shipping. Please note that the method may be changed (Yu-Yu ⇔ Raku-Raku) depending on the size after packaging. I will take measures to prevent water damage and folding as much as possible, but I may use recycled packaging materials. No prior comments are required before purchase. Instant purchase is welcome. Thank you very much.
