These 'Caverns and Rabbits' tank tops are super easy to use. Just put them on and enjoy the comfort! For men and unisex styles, you can choose from sizes XS to 2XL. Women have a wider range from XS to 4XL. When it comes to cleaning, use cold water and wash them inside out with clothes of similar colors. Only use non - chlorine bleach if needed. After washing, it's best to hang them to dry. 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. And don't iron or dry clean these tank tops to keep them in great shape.
