【Sleep Soundly, Silky Smooth Hair】 Friction from tossing and turning against your pillow damages your hair, leading to breakage, split ends, and tangling. Pillowcases made of thick, stiff materials put even more stress on your hair. Silk, with its fine and soft fibers, thoroughly protects against friction damage. It also provides high moisturizing properties to replenish moisture. 【Comfortable Sleep】 Silk also excels in breathability and moisture wicking, making it less likely to feel stuffy even if you sweat during the night. It supports comfortable sleep with a smooth, silky touch until morning. Furthermore, it's made of the same protein as human skin, making it gentle on the skin. 36-13-60
