Here's how to use and take care of your Jurassic Crossing long - sleeve t - shirt. First, just put it on and enjoy looking cool! When it's time to clean it, use your washing machine on a cold cycle. Turn it inside out and wash it with clothes of similar colors. If it gets really dirty, you can use non - chlorine bleach. After washing, it's best to hang it to dry. But if you're in a hurry, you can use the tumble dryer on a cool or low - heat setting. Remember, don't use fabric softener because it might make the colors fade. And don't iron or take it to the dry cleaner. By following these simple steps, your t - shirt will stay in great shape for a long time.
