These Glitchygorilla Smoking Diamond hoodies are super easy to use. Just put them on and you're good to go! When it comes to washing, make sure to turn them inside out and wash them in cold water with similar colors. Only use non - chlorine bleach if you really need to. After washing, it's best to hang them dry, but you can also use the tumble dryer on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these hoodies as it might damage them. They're available in a range of sizes from S to 4XL, so you can find the perfect fit.
