Using these belts is super easy. Just wrap the belt around your waist through the belt loops of your pants or skirt. Then, buckle it up to your desired tightness. When it comes to maintenance, use a soft, damp cloth to gently wipe the belt clean. Avoid using harsh chemicals or abrasive materials as they may damage the polyurethane. Also, remember to store the belts in a cool, dry place to prevent any warping or damage. Due to the warning about exposure to certain chemicals, be careful not to put the belt in your mouth or let it come into contact with food.
