Using these belts is easy. Just wrap the belt around your waist and fasten it with the pearl buckle. You can wear them with various outfits to add a touch of style. As for maintenance, keep them away from sharp objects to avoid tearing the elastic part. Also, clean them with a mild soap and water if they get dirty. Remember, due to the chemicals they may contain as mentioned in the California Proposition 65 warning, handle them with care and don't let children play with them without supervision.
