Tetta Sugimoto is in both! ♪ I wanted to read them, so I bought the whole set at a flea market and bookstores. Please give them a read if you'd like. Please judge the condition based on the photos. Please consider purchasing, understanding that these are used items and have been stored at home. The items will be packaged and shipped in recycled cardboard boxes. ※ Immediate purchase is OK. However, as they are also listed on other sites, the first person to purchase will be given priority. I will be periodically lowering the price, so please refrain from price negotiations m(_ _)m Thank you for looking.
