These classic black Hollywood California caps are great for daily wear. Just put them on your head and adjust the strap if needed. When you're done wearing them, store them in a dry place to keep their shape. Be aware of the California Proposition 65 warning about the chemicals in the product. Avoid prolonged contact with your skin and don't let kids chew on the caps. If they get dirty, use a soft brush and mild soap to clean them gently.
