Highest quality Long Fibre 100% pure Mulberry silk ( 22 momme, 6A grade). No Heat Hair Curler full set with hair clip! The best quality Organic silk Hair Curl Set in the market! With super soft cotton filled padding that is so comfy to sleep on ( watch out from hard tube stuffed curlers that are even hard to bend and too even filling - it is hard sponge tube - pool noodle, not soft padding ;)) Also our curler is round shape so it does make round curls not flat;) MATERIAL: Pure SILK 100% natural Mulberry Long fiber. The length of the silk is important in creating high-quality fabric. Long fibers make long, smooth surfaces, which is why silk reflects light and has that special shine.
