To use this backpack, start by opening the main zip - top compartment. You can put your books, notebooks, and other large items in there. The front compartment is great for storing smaller things like your phone, keys, or a calculator. Just unzip it and use the inside open and cell pockets to keep everything organized. The side mesh pockets are perfect for holding a water bottle or a small umbrella. When adjusting the shoulder straps, make sure they're comfortable on your shoulders and not too tight or too loose. To maintain this backpack, keep it away from sharp objects that could tear the canvas. If it gets dirty, you can use a mild detergent and a soft cloth to gently clean the surface. Avoid machine - washing it to prevent damage to the zippers and lining.
