100% PURE 22 MOMME MULBERRY SILK – Made from premium 6A-grade mulberry silk inside and out. Smooth, breathable, and gentle on delicate facial skin to support a more restful sleep and help maintain skin hydration. SOFT, NON-ADJUSTABLE ELASTIC STRAP – Designed with a comfortable, silk-covered elastic band for a secure, lightweight fit. One-size design fits most head sizes (approx. 20–24 inches). Strap length and tension are optimized for comfort without hardware or metal adjusters. COMFORT-FIT SHAPE – The mask’s contoured design rests gently on the face. Fit and light-blocking performance may vary based on head size and facial structure, and customers who prefer an adjustable strap should review sizing details before purchase. LIGHT-BLOCKING DESIGN – Provides a high level of blackout by draping naturally over the eyes with a soft, padded inner layer. Because every face shape is different, some users may experience slight light entry depending on positioning. OEKO-TEX STANDARD 100 CERTIFIED – Made without harmful chemicals or dyes. Safe for daily use and suitable for sensitive skin. Naturally hypoallergenic, cooling, and moisture-preserving to help reduce friction, tugging, and morning creases. SKIN & HAIR BENEFITS – Pure silk helps maintain moisture balance, supports smoother skin during sleep, and reduces friction that can cause creasing or hair breakage. Ideal for beauty rest and nightly relaxation routines. This sleep mask features a non-adjustable, silk-covered elastic band designed for a soft and secure fit. Because fit preference varies, some customers may find the mask tighter or looser depending on their head size. We recommend checking the sizing details to ensure proper comfort and coverage.
