Using these pillow covers is a breeze. Just unzip the cover and insert your pillow. You can use them indoors on your sofa, bed, or outdoors on your patio furniture. They'll add a pop of color and style to any space. When it comes to maintenance, these pillow covers are water and UV resistant, so they can handle some light splashes and sun exposure. But it's still a good idea to bring them indoors during heavy rain or extreme weather. They're also resistant to mold and mildew, but try to keep them dry and well - ventilated. There's no need for assembly, so you can start using them right away. And remember, you're getting the exact product based on the options you choose on the page.
