These Ninjutsu Masters tank tops from Dracula Byte are super easy to use. Just put them on and enjoy the comfort. When it comes to washing, use cold water and turn them inside out. Wash them with clothes of similar colors. Only use non - chlorine bleach if needed. After washing, you can hang them to dry for the best results, or you can use a tumble dryer on cool or low heat. Don't use fabric softener because it might make the colors fade. Also, don't iron or dry clean these tank tops to keep them in good condition.
