"Soft and sumptuous, this Oxford pillowcase is packed full of positives to ensure you a sound and silent night's sleep. Amazingly soft to the touch, with the best drape of all fabrics, silk regulates your body temperature by trapping air next to your skin, keeping you warm in winter and cool in summer. Silk also offers fabulous health and beauty benefits - it proactively helps to retain moisture in your skin and hair, helping minimise wrinkles and prevents ""bed head"", frizz and static. Made with organic silk and also Global Organic Textile Standard (GOTS) certified. This assures that high social and environmental standards of manufacture have been met across the entire textile supply chain. We recommend washing this silk product on a delicate cycle, using a specialist silk detergent and washing inside out in a laundry bag. We also recommend not to use fabric softener, to keep away from direct sunlight and to lightly press on the reverse with a cool iron."
