This is a calm, dark navy color, so I think it will be very useful for school and commuting. The size is just big enough to fit A4 documents. If it's thick, it won't fit. It also has a zipper, making it easy to use! The retail price is around 90,000 yen, so it's a great deal (^-^) It's hardly been used, so the condition is good, but please understand that it is a used item. Size: Approximately 26cm high x 37cm wide x 10-12cm deep!
