This traveling case is designed for business people to make it much more convenient when they perform official business on a long journey. It is a combination of several separable components. Therefore, you can choose the components you need and decide the size of your suitcase based on how many days the trip takes and how many things you take. At the airport, you can just open the bag and turn the computer on doing business rather than doing one more action taking out the computer. Arriving at the destination, you can use it as a briefcase so that its unnecessary to prepare another briefcase or arrange things inside.
