Good Housekeeping Tried and Tested: The experts at Good Housekeeping Magazine have labeled our 100% Pure Mulberry Silk Pillowcase a "Winner" and "All-Star Standout." | Luxurious Bedding: Our pillowcase is made of 100% long strand, Grade 6A Pure Mulberry Silk. There is silk on BOTH sides of the pillowcase! The density of silk is measured by momme. The higher the momme, the more silk. We have added a unique side entry that is slightly offset. The pillowcase can be used as both a sham or pillowcase. An oversized, envelope flap ensures the pillow will remain securely inside your pillowcase. | Easy Care Instructions: Dry clean or hand wash are the best methods. You can also machine wash on the gentle cycle. We suggest to use a mesh wash bag when do so. Lay flat to dry. | Variety of Colors and Sizes: We offer a wide range of colors. Choose from: White, Light Blue, Light Green, Silver, English Rose, Deep Lavender, Burgundy, Taupe, Black, Navy or Hunter Green. Our pillowcase comes in Queen and King sizes.
