This Kaiju Croissant sweatshirt is really easy to use. Just put it on and enjoy its comfort. When it comes to cleaning, machine wash it cold inside out with similar colors. Only use non - chlorine bleach if it's really dirty. After washing, you can either hang it to dry for the best look or tumble dry it on cool or low heat. But be careful not to use fabric softener because it can make the colors fade. Also, never iron or dry clean this sweatshirt to keep it in good condition.
