These hoodies are super easy to use. Just put them on and you're ready to go! When it comes to washing, remember to turn them inside out and wash in cold water with similar colors. If they get dirty, you can use non - chlorine bleach, but only when really needed. After washing, it's best to hang them up to dry. You can also use the tumble dry setting on cool or low heat. But stay away from fabric softener because it might make the colors fade. And don't try to iron or dry clean these hoodies, as it could damage them. Enjoy your stylish and comfortable hoodies!
