Using these pillow covers is a breeze. Just unzip the cover and insert your pillow. You can use them indoors on your couch, bed, or outdoor patio furniture. They're great for adding a touch of color and style to any space. When it comes to maintenance, spot clean them with a mild detergent and water. Avoid using harsh chemicals as they might damage the UV - protected polyester material. Keep them out of direct sunlight for long periods to prevent color fading. And since they're water - resistant, a light rain won't harm them, but it's best to dry them if they get wet. These pillow covers don't require any assembly, so you can start using them right away.
