OLESILK Sleep Mask, 100% Natural Mulberry Silk Eye Mask for Women and Men with Adjustable Strap, Large in Size, Blindfold All Night Sleep, Black

100% REAL NATURAL SILK: This eye mask is made in an eco-friendly studio using natural 19mm premium silk on both sides. It protects your skin and hair from friction and gives you a silky smooth night's sleep PERSONALISED DESIGN: We have taken the shape of a cloud and increased the size of the eye mask, while at the same time designing a "cloud curve" to ensure it fits comfortably without pressing on your skin and blocks out virtually all ambient light. ADJUSTABLE STRAP: You can freely adjust the fit of the eye mask to give you the most comfortable experience BLACKOUT: The high-density silk and the unique "cloud curve" can not 100% guarantee that no light will pass through, in fact, no material or design can give such a guarantee. But what we can guarantee is a perfect night's sleep, day or night. TIPS: We recommend that you wash your eye masks every one to two weeks. It is better to hand wash and dry naturally to ensure the longest possible life of 100% natural silk
