Using this backpack is a breeze. First, open the flap - style closure and buckle to access the main compartment. You can store your notebooks and folders here. For your laptop or tablet, place them in the respective padded sleeves. The front zippered pocket is for small items like your keys, phone, or USB drives. Just hook your keys to the key leash for easy finding. The side pockets are perfect for your water bottles. When it comes to maintenance, use a soft, damp cloth to clean the backpack regularly. Avoid using harsh chemicals as they may damage the material. Keep it away from sharp objects to prevent tears. And make sure not to overload it beyond its capacity to maintain its shape and functionality.
