Using these 'Guillermo the Slayer' hoodies is easy. Just put them on and enjoy the stylish look. When it comes to maintenance, machine wash them cold and turn them inside out to protect the prints. Wash with like colors to prevent color bleeding. Only use non - chlorine bleach if stains appear. After washing, it's best to hang them dry to keep their shape. But if you're in a hurry, you can tumble dry on cool or low heat. Don't use fabric softener as it can fade the colors. Also, avoid ironing and dry cleaning to ensure the longevity of your hoodies.
