Using this sling bag is a breeze. Simply adjust the strap to your desired length and put it over your shoulder. You can carry it on either side based on your comfort. For everyday use, it's great for holding your phone, wallet, keys, and other small essentials. When it comes to maintenance, keep it away from sharp objects to avoid scratches on the PU leather. If it gets dirty, use a soft, damp cloth to gently wipe the surface. Don't soak it in water or use harsh chemicals as this may damage the material. Store it in a cool, dry place when not in use to keep its shape and quality intact.
