These beanies are super easy to use. Just slip them on your head and you're ready to go! They're great for casual outings, skiing, or just to keep you warm on a cold day. When it comes to maintenance, you can hand - wash them in cold water with a mild detergent. Avoid using bleach as it may damage the fabric. Hang them to dry to maintain their shape. Remember, due to the California Proposition 65 warning, handle the product with care as it contains chemicals that can be harmful. Keep it away from children and pregnant women as much as possible.
