I love love LOVE this product! I have tried many brow shapers/keepers/fillers, some very high end, and this is by far the winner! The tiny brush grabs my brows where they are most sparse, and the formula coats and lengthens those areas. Where my brows are fuller, it locks them into place, and the formula doesn't smudge or drip off in the heat. I am glad that this product was recommended to me because I'm in love :)
