This textbook was purchased in April 2024. It was used for university classes. It was used for only three months during the spring semester and has been stored at home since then. It's still in good condition, and based on a casual inspection, there are no markings inside. There is some color transfer on the cover band on the fifth page. Other than that, it's like new, with no folded pages or stains (as far as I can tell). This is for first-year students who entered this year, or for upperclassmen who are taking classes that use this textbook. I will offer a small discount to university students. Original price: 1,800 yen + tax
