Using this backpack is a breeze. Just unzip the main compartment to access your belongings. The various interior pockets are great for organizing your items - use the cell phone pocket for your phone, the interior slot pocket for cards or small notebooks, and the computer interlayer to safely store your laptop. When carrying it, adjust the arcuate shoulder straps to a comfortable length. For the handle, you can hold it briefly when needed. As for maintenance, avoid exposing the backpack to sharp objects to prevent scratches on the PU leather. If it gets dirty, gently wipe it with a soft, damp cloth. Don't use harsh chemicals as they may damage the material. Store it in a dry place when not in use to keep it in good condition.
