Using this backpack is easy. Just unzip the main compartment and put your books, notebooks, and other big items inside. You can use the front zip pocket to keep small things like your phone charger, keys, or calculator organized. The pen/pencil pockets are great for keeping your writing tools handy. The side mesh pockets are perfect for holding a water bottle. When it comes to cleaning, you can use a damp cloth to wipe the clear PVC part. Avoid using harsh chemicals as they may damage the plastic. Also, don't overstuff the backpack as it might affect the durability of the zippers and straps. Adjust the shoulder straps to a comfortable length so you can carry it without any strain on your back.
