This is an older model tanker 3-way briefcase. The size is the larger one, with dimensions of: W: 450mm / H: 330mm / D: 180mm The color is black. I used it not for everyday use, but for trips when I had a lot of luggage, so I think it's relatively clean. The paint on the metal fittings tends to peel easily, so please take that into consideration. I didn't use it much as a backpack, so it's relatively clean. Please refer to the photos for the condition. This is a large 3-way briefcase that can also hold A3 documents. In addition to the two-layer structure, the main compartment has a full-open round zipper, and it has a wide gusset, making it a high-capacity item. The interior is equipped with straps to secure luggage, making it convenient for storing items such as changes of clothes.
