SIGNATURE DESIGN – This pillowcase is cut and sewn to fit the unique shape of the Omnia pillow by Sleep & Glow, so that the fabric doesn’t wrinkle in the cradles and doesn’t affect the skin of your face, neck, and shoulders. Tight fit of the pillowcase prevents your pillow from escaping during your sweet dream. 100% NATURAL SILK – This pillowcase is made from 19mm Grade 6A Mulberry Silk. This is natural silk, that is known as luxurious and unbelievably soft to the touch. It also maintains a lower temperature, which has beneficial effects for your skin. ANTI-AGING – Aula pillowcase not only protects your Sleep & Glow beauty pillow, but also enhances its anti-aging effect. HEALTY SLEEP – This pillowcase helps your skin stay fresh and hydrated when you sleep. The silk doesn’t absorb face creams and helps prevent hair breakage and tangling. MAXIMUM HYGIENE - Beauty and sleep experts recommend changing your pillowcase once every 2-3 days for good sleep hygiene. By having several pillowcases on hand, you can swap them to do some laundry and always sleep on a fresh pillowcase.
