This personalized long - sleeve Christmas pajama T - shirt is easy to use. Just put it on and enjoy the holiday spirit! When it comes to maintenance, you can simply toss it in the washing machine as it's machine - wash safe. However, to keep the colors vibrant and the fabric in good shape, it's best to use a gentle cycle. Also, be aware that the preview images might look a bit different in color from the real T - shirt because of the lighting when we took the photos or how your monitor shows colors. And don't forget, the artwork on the shirt is copyrighted, so no unauthorized reproduction, okay?
