The silk sheets items are ready for use. While silk always wrinkles easily after packaging and shipping. The wrinkles will disappear after hours of air. You could also wash them before first use. Make it smooth without wrinkles and smells better:)We’d suggest that you scrutinize the item after receiving if all right then you could have them washed if you like. Iron when slightly damp using a cool setting. Always iron on the inside. Here is some silk care notice for you. I hope it will help.-Never wash silk with chlorine bleach. It could damage the natural fibers-Avoid drying silk in direct sunlight. Prolonged exposure can cause damage or fading-Never tumble dry silk – the heat can also cause damage or shrinking-Use a mild, non-biological detergent. A detergent specially designed for the purpose is best for washing silkMore questions, please contact us at service@thxsilk.com
