This is a Japanese-made bag made of synthetic leather from Morino Hanpu, known for its durability and water resistance. Morino Hanpu Sengu Kogyosho is a long-established manufacturer founded in Yokohama in 1914, and also supplies products to the Japan Maritime Self-Defense Force. The lightweight, yet durable and glossy leather is suitable for business use. It has a large capacity that can easily fit B4 size items, but I am selling it because it is too big for me. I have only used it a few times, so it is relatively clean, but please refrain from purchasing if you are looking for perfection. The price is about a quarter of the purchase price, so I would appreciate it if someone would use it. There are five pockets, two on the outside and three inside. It also comes with a removable shoulder strap, making it easy to use. Thank you very much. Thank you for looking.
