These books are great for anyone interested in Japanese history. You can simply sit back and start reading to learn about the Kamakura period. When handling the books, be gentle, especially with Volume 1's dust jacket as it's tearing. To keep them in good shape, store them in a dry and cool place away from direct sunlight. Avoid getting the pages wet. If you want to clean the slip case, use a soft, dry cloth to gently wipe off any dust.
