Tafts silk pillowcases are 100% Mulberry Silk and never mixed with other fabrics. Silk fibers are rich in proteins that have natural anti-aging qualities. They prevent wrinkles and skin from getting acne. Pure mulberry silk acts as a natural thermo-regulator, keeping you cool in summer and warm during winter. The concealed envelope design keeps your pillow in place at night. It is invisible and seamless.
