These coastal crab pillow covers are easy to use. Just unzip the cover and insert your pillow form. You can place them on sofas, chairs, or outdoor loungers to instantly spruce up the area. For cleaning, simply spot - clean with a mild detergent and let it air dry. Avoid using harsh chemicals as they may damage the material. Keep them away from direct sunlight for long periods to prevent color fading. They're resistant to mold, mildew, water, and UV, but it's still a good idea to store them in a dry place when not in use. These pillow covers don't require any assembly, so you can start using them right away.
