How to use: Just put on your Pixel Nightmare long - sleeve sweatshirt and enjoy the comfort. When it's time to clean, remember to machine wash it cold, inside out with similar colors. Only use non - chlorine bleach if it's really dirty. Hang it to dry for the best look, but if you're in a hurry, you can tumble dry it on a cool or low - heat setting. Be careful not to use fabric softener as it might make the colors fade. Also, don't iron it or take it to the dry cleaner. That way, your sweatshirt will stay in great shape for a long time.
