My child used this for studying for the Self-Defense Forces entrance exam. It can also be used for other exams, not just the SDF. There are no markings, but please forgive me if I missed any. I will ship it in a plastic bag and a handmade paper bag. Please refrain from purchasing if you are a perfectionist. ♥ I'm selling two books for 300 yen from the business books on another page and Tono Shibata's "Kujikenai de" (without cover). Please comment if you'd like them.
