This backpack is super easy to use. Just unzip it to put your things inside. You can carry it on your back when you go out for a walk, to school, or for a trip. Make sure to close the zipper tightly to keep your items safe. When it gets dirty, you can gently wipe it with a damp cloth. Avoid using harsh chemicals as they might damage the nylon material. Also, don't overstuff it to keep its square shape intact.
