25 Momme Mulberry Silk Exterior/ Silk Fill LUXURY SLEEP: Our 25 momme sleeping mask is made from certified organic mulberry silk. We only use Grade 6A long-strand Mulberry Silk because it's the highest quality available. While other brands use 22 Momme or less, our eye mask has 13% more silk! HIGH-QUALITY DESIGN: Our sleeping mask is made from Mulberry Silk on both sides and filled with silk. This eye mask features dual anchor points and an adjustable elastic band to help relieve pressure around the eyes. TRIED AND TESTED: The experts at the Good Housekeeping Institute have tested and approved our silk sleep mask. SILK BENEFITS: Silk's naturally smooth, luxurious surface is gentle on skin. Reduced friction may help minimize wrinkles and creases. Unlike cotton, silk helps retain the natural oils and moisture of your skin. Our undyed, natural white silk is hypoallergenic. CARE INSTRUCTIONS: Dry clean or hand wash. Use cold water and a mild detergent formulated for delicate fabrics. Lay flat to dry.
