To use these Samus symbol men's shirts, simply put them on and enjoy the stylish look. When it's time to clean, machine wash them cold inside out with similar colors. Only use non - chlorine bleach if necessary. After washing, it's best to hang them to dry. You can also tumble dry on cool or low heat. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these shirts to keep them in good condition.
