Using these Soulkr's Summoner Academy hoodies is as easy as just putting them on. They are suitable for various casual occasions. When it comes to washing, make sure to turn them inside out and use cold water. Wash them with similar colors to avoid color bleeding. Only use non - chlorine bleach if there are stubborn stains. After washing, it's best to hang them to dry to keep their shape. If you're in a hurry, you can use the cool or low - heat setting in the dryer. But be careful not to use fabric softener because it can make the colors fade. Also, don't iron them or take them to the dry cleaner as it might damage the fabric and the prints.
