Each slip pure silk sleep mask was refined and perfected over the course of ten years to ensure it delivers the most restorative beauty rest. Crafted from long-strand mulberry silk both inside and out, they protect delicate skin from the tugging effects of tossing and turning. This contour sleep mask was specially designed with eyelashes and eyelash extensions in mind. The mask sits away from your eyelids, allowing them additional space to rest as you sleep.
