Early luggage was made of wood or other heavy materials. With the popularity of air travel, luggage tends to be made of lighter hard plastic or cloth. Most models also have a built-in wheel, which can be pulled easily by a pull bar. Since 2010, there have also been luggage with 4 wheels, which can not only rotate 360 degrees, but also can be pushed easily on the level without effort
