Using this bag is a breeze. You can wear it on one shoulder or crossbody according to your preference and the situation. When putting things inside, start with bigger items like your phone at the bottom of the main bag. You can then place smaller items like keys around it. To keep your bag in good condition, avoid contact with sharp objects that could scratch the leather. If it gets dirty, gently wipe it with a soft, dry cloth. Don't expose it to extreme heat or cold as this may damage the leather. When not in use, store it in a cool, dry place.
