These Sketchdemao hoodies are really easy to use. Just put them on and you're ready to go! When it comes to cleaning, remember to machine wash them cold and turn them inside out. Wash with clothes of the same color to avoid color mixing. Only use non - chlorine bleach if there are stains. After washing, you can either hang them up to dry or use the tumble dry setting on cool/low heat. Don't use fabric softener as it can make the colors fade. And never iron or dry clean these hoodies to keep them in good condition.
