This is a Flying Horse horsehide business bag. Originally, it's a multi-functional business bag that can be used in three ways: as a backpack, briefcase, and shoulder bag. However, since I've been using it as a backpack and briefcase, I've lost the shoulder strap. In addition to the large main compartment, it has separate storage spaces and various pockets, making it easy to organize. With its outstanding storage capacity, even for business trips, and its design that allows it to be used as a backpack, it's a great item that can be used for both business and casual occasions. Rear storage compartment that can safely hold a PC The rear storage compartment has cushioning, making it ideal for storing PCs and tablets. I've loved and used it for many years, so there are some scuffs on the leather and a part of a button is missing (see photo 11). It's made of durable horsehide, so it can still be used for a long time. Excellent storage capacity!!! When used as a backpack: Height: Approximately 43 cm Width: Approximately 30 cm Depth: Approximately 16 cm
