Using these pillow covers is a breeze. Simply slide your pillow inserts into the envelope-style covers. You can use them indoors on your couch, bed, or outdoor furniture to add a coastal vibe. To keep them looking great, spot clean with a mild detergent and a soft cloth. Avoid machine washing or dry cleaning to prevent damage. Keep them away from sharp objects to avoid tears. These covers are mold and mildew resistant, but it's still a good idea to keep them dry if used outdoors. Enjoy the comfort and style they bring to your space!
