Smir Pillow Cases SetRelaxing onto soft, warm clouds of cotton and cashmere twill that is what it is like to lie back on a Kash pillowcase. Strictly created for winter nights and manufactured with a diagonal weave, Kash pillowcases are extremely soft and delicate to the touch, but also very hard wearing, available in a range of subtle colours and machine washable. Each set includes two pillow cases.
