I am opening this item for listing. It is a new, unused item, so I believe it is in beautiful condition. However, it has been stored at home. I kindly ask for purchases from those who understand that this is a used item. (^^) The item will be shipped in simple packaging. ◯ Perfect for checking before tests! ◯ Briefly explains the year of the incident and its cause! ◯ Illustrations help with visualization! ◯ Learn with question-and-answer format on the front and back of the cards!
