Yoshida & Co. PORTER / Porter 2-WAY BRIEFCASE W: 420mm / H: 300mm / D: 90mm Black Material: Exterior: Tarpaulin (Bonding Process) Interior: Nylon Ox (Acrylic Coating) I used it very little after purchasing it because I changed jobs, but it is a used item, so please refrain from purchasing if you are sensitive to such things. Please check the photos for the age-related deterioration on the handles and the top corners. Product Details: The "PORTER DEVICE" series is attractive for its high functionality, pursuing added value in business bags by using water-resistant tarpaulin material. The main material uses fabric made of 0.35mm thick tarpaulin with a bonding process, making it a high-performance material that is not only water-resistant but also lightweight and durable. The leather used for the handles and some accessories is also water-repellent, so you can use it without worrying about the weather.
