We pay close attention to inventory management, but occasionally items may be out of stock. We welcome inquiries about stock availability before purchase. Also, the images are of the actual items, but the colors and condition may not appear exactly as they are in reality. In particular, yellowing may appear whiter than it actually is. Please consider the description along with the images. [Product Condition] The main body has some yellowing. It can be read as a regular used book. [Price Reduction/Splitting of Sets] We generally do not offer these. [Shipping Method] We will determine the shipping method, such as Yu-Mail, based on the size of the item. For set items, shipping may be split into 2-3 packages. Yu-Mail does not deliver on weekends and holidays. If you need the item urgently or have a preferred shipping method, please contact us before purchasing. [Packaging] We will take measures to prevent water damage, but the packaging will be simple, without cushioning material. [For those who want the product ID, etc., written on the package] We are very sorry, but we cannot accommodate this request as it complicates our operations. Please add it to your address yourself.
