Real Silk, No More Eyelash Damage/Breakage [SEP] This sleep mask is wonderful.  It's thin, soft & made of real silk.  The elastic band is comfortable & adjustable.  I've 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've found to that old mask & I absolutely love it.
