We spend a third of our lives in bed, so what you sleep on is important. Silk fibers are significantly less absorbent than many other fibers, so they help keep your skin's moisture and expensive face and hair products where they belong-on your face and hair, not your pillow. Ordinary pillowcases and masks can cause hair to pull and tangle throughout the night, leading to bed head in the morning and potentially damaging hair. Slipsilk can help reduce friction, too, which also aids in reducing stretching and tugging on delicate facial skin. slip for beauty sleep hair ties are made with Slipsilk, the same silk used to make the brand's award-winning pillowcases. Each has a wide surface area and is designed to reduce those annoying ridges caused by regular hair scrunchies.Collection includes:- Pure Silk Pillowcase- Pure Silk Sleep Mask- Skinny Hair Ties (2-pack)- Hair Tie Pillowcase is 30" x 20" Pillowcase is 100% mulberry silk; sleep mask is 100% mulberry silk and silk filler; hair ties are 100% mulberry silk Pillowcase is machine or hand wash, air dry; sleep mask is hand wash, air dry Imported
