These White Hollywood Classic Caps are super easy to use. Just put them on your head and adjust the strap at the back for a comfortable fit. They're great for a sunny day out, a casual walk, or even a Hollywood - themed party. As for maintenance, you can spot - clean them with a mild detergent and a soft cloth. When not in use, store them in a cool, dry place. Also, remember the California Proposition 65 warning. Avoid long - term contact with the chemicals in the cap, and don't let kids chew on them.
