Use a soft brush or cloth to regularly remove dust and dirt, gently brushing in the direction of the weave to protect the delicate paper fibers. Remember, paper hats are not water-resistant, so avoid exposing them to water and keep them dry. If the hat gets wet, pat it dry with a clean cloth and let it air dry naturally. When storing, choose a cool, dry place away from direct sunlight and heat sources, and avoid placing heavy objects on top to preserve the hat's shape.
