These Hypertwenty Black Wizard hoodies are super easy to use. Just put them on and enjoy your day! When it comes to cleaning, remember to machine wash them cold and turn them inside out. Wash with similar colors to keep the colors vibrant. Only use non - chlorine bleach if you really need to. After washing, hanging them to dry is the best option. But if you're in a hurry, you can tumble dry on cool or low heat. Don't use fabric softener because it can make the colors fade. Also, don't iron or dry clean these hoodies to keep them in good condition.
