This sweatshirt is super easy to use. Just put it on and enjoy the comfort and style. When it comes to washing, you can simply toss it in the washing machine as it's machine - wash safe. However, to keep its shape and color for a long time, it's better to use a gentle cycle. Be aware that the preview images might look a bit different from the real sweatshirt in terms of color. This is because of the lighting when we took the product photos or how your monitor displays colors. So, don't be surprised if there's a slight variation. And that's all you need to know to enjoy your personalized cat - themed sweatshirt!
