Using this personalized long - sleeve T - shirt is as easy as putting on any regular shirt. Just slip it on and enjoy the unique look. When it comes to maintenance, you can safely throw it in the washing machine. But keep in mind that because of the copyrighted artwork, it's best to use a gentle cycle to preserve the design. As for the color differences, don't be surprised if the shirt you receive looks a bit different from the preview image. This is normal due to lighting during the photo shoot or your monitor settings.
