Using this backpack is super easy. Just adjust the straps to your comfort and put your stuff inside. You can use the side pockets for smaller items like keys or a phone. When you're in a dark place, the glow - in - the - dark details will really stand out. As for maintenance, wipe it with a soft, dry cloth to keep it clean. Avoid exposing it to harsh chemicals or excessive moisture as this could damage the vegan leather and the details. Also, don't overstuff it to prevent the hardware from getting loose. And remember, since it's an officially licensed product, take good care of it to keep it looking great for a long time.
