SIGNATURE DESIGN - cut and sewn to fit the unique shape of the Sleep&Glow Omnia pillow, so that the fabric doesn’t get wrinkled in the cradles and doesn’t affect the skin on your face, neck, and shoulders. ANTI-AGING EFFECT - improves the effectiveness of the Sleep&Glow Omnia pillow. HIGH QUALITY FABRIC - The pillowcase is made from 100% Tencel. It’s a natural fabric made of eucalyptus fiber, which is smoother, softer to the touch and more breathable than cotton. Tencel has hypoallergenic and bacteriostatic properties and is suitable for sensitive skin. We source custom woven Tencel of high density to provide high durability, so that it keeps its properties even after multiple washes.
