Not only is a backpack a necessity for you to move papers and odds and ends around, it's also an important reflection of your personal style. It's no more practical than a rucksack, mail bag, or brown paper bag, but the way it looks reveals your personality.Don't jump on the bandwagon. High-quality backpack should be durable, far more than any fashion trend can replace. Stick to basic colors and styles. The mail-bag briefcase, with its soft body and straps, is becoming more and more common. It's easy to carry and it's easy to carry things. It may wrinkle your suit, but it's still a great way to go to work or work in a more casual environment.For the elderly, who demand the trappings of a scholar or a lawyer, a slightly dated briefcase gives you an air of authority; But holding it in the hands of a young person can be too sloppy. Young people who have just started work should buy a new briefcase and let it become more and more sophisticated with you after years of hard work.
