Using your Mutant Snapper t-shirts is easy - just put them on and enjoy their comfort! When it comes to maintenance, machine wash them cold and inside out with similar colors. Only use non - chlorine bleach if necessary. Hang them to dry for the best results, but if you're in a hurry, you can tumble dry on cool or low heat. Remember, fabric softener can make the colors fade, so skip it. Also, don't iron or dry clean these shirts to keep them in good shape.
