real silk no more eyelash damage breakage [SEP] this sleep mask is wonderful it is thin soft made of real silk the elastic band is comfortable adjustable i have gone through so many sleep masks since my fav from the natural food store made of silk cotton filled with lavender but thin not puffy finally gave up the ghost if this had lavender buds in in omg it would be perfection anyway this is the closest i have found to that old mask i absolutely love it
