Please understand. The inside pages are relatively clean, but as they have been stored for several years, please only purchase if you understand this. As these are used items, please refrain from purchasing if you are looking for perfection or are sensitive. The books will be placed in a PP bag and shipped via Nekoposu. To offer them at a lower price, they will be shipped with simple packaging. Please understand. The sticky notes will be removed.
