Using this belt is super easy. Just thread the belt through the belt loops of your pants or skirt, and then fasten it using the needle buckle. You can adjust the length according to your preference within the 60 - 80cm range. When it comes to care, avoid getting the belt wet for a long time as it's made of imitation leather. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean. Also, store it in a dry place when not in use to keep it in good condition. And remember, since the buckle is made of copper, try to avoid contact with harsh chemicals to prevent it from tarnishing.
