These Bat Teerion women's t-shirts are really easy to use. Just put them on and enjoy the comfort! When it comes to washing, you can use your washing machine. Set it to a cold cycle and turn the shirts inside out. Wash them with clothes of similar colors. If they get dirty and need bleaching, use non - chlorine bleach. After washing, hanging them to dry will give the best results, but if you're in a hurry, you can tumble dry on cool or low heat. Remember, don't use fabric softener because it can make the colors fade. Also, stay away from ironing and dry cleaning as they might damage the shirts. With these tips, your Bat Teerion t - shirts will last a long time.
