I recommend a 24-inch suitcase, pink. I like this color because I am a girl. It is recommended to use a password lock in the suitcase to prevent theft. If you forget the password, you can open it with the key. The suitcase can be pulled, so it is more convenient to walk. When you pull it to the door of the dormitory stairs, lift it directly and put it in the dormitory. After graduation, pack up luggage belt and go.
Therefore, it is recommended that college students use suitcases of more than 20 inches. Not too small to prevent putting down a lot of things. Don't care too much about the appearance of the suitcase, just suit yourself.
