Briefcases for men are not just a bag for putting documents and stuffs for work, but now they are also more for fashion. When I was a child, most common briefcases are designed rectangular boxes with sharp edges but now, the designs are softened. The materials are also changed. These days, leather briefcases are more common. Many kinds of leather briefcases for men with stylish design are also used as a prestige than just carrying working files.
