Using these pillow covers is a breeze. Just unzip the cover and insert your pillow insert. They're great for sprucing up your indoor couch or outdoor patio furniture. When it comes to cleaning, spot - clean them with a mild detergent and let them air dry. Avoid direct sunlight for long periods to prevent color fading. These covers don't need any assembly, so you can start using them right away. And remember, they're not for commercial use. If you want to keep them looking their best, handle them gently and keep them away from sharp objects that could tear the fabric.
