These pillow covers are really easy to use. Just unzip the cover and insert your pillow inside. You can use them indoors on your sofa, bed, or outdoors on your patio furniture. They're great for adding a splash of color and style to any space. When it comes to maintenance, it's a piece of cake. If they get dirty, simply spot - clean them with a mild detergent and a soft cloth. Avoid using harsh chemicals as they might damage the fabric. Since they're UV and water resistant, they can stay outside in light rain or under the sun, but it's a good idea to bring them inside during heavy storms or extreme weather. And remember, these are not for commercial use, so keep them for your personal enjoyment at home.
