1Made of santin material, soft and comfortable, santin pillowcases are the perfect choice for a comfortable sleep. 2With our pillowcase, your hair will be soft and smooth when you wake up in the morning, so you can relax. Satin pillowcases keep your hair from tangling and reduce breakage. 3Sleeping on our hypoallergenic nonirritating satin pillowcase can also help your skin. When you sleep, reduce the frictional pull on your skin and you will experience fewer lines of sleep, which over time can reduce the appearance of wrinkles. 4Sleeping without a zipper will poke you. Instead of zippers, our pillowcases open and close with envelopes. The soft pillowcase holds the pillow firmly in place while you rest. 5Santin fibers are excellent for regulating temperature. This keeps our satin pillowcase cool while you sleep, allowing you to have a good night's sleep. 6Our pillowcases are of high quality, luxurious and affordable.
