Birchbox and I gave it the ultimate test today. Since we're Jewish and don't celebrate Christmas, we have a long-standing tradition of going to the movies and this year we saw War Horse. Even though it's set during a world war, there is an emotional undertone and I bawled for the last 20 minutes or so (I went through 3 tissues). After the movie, on the ride over to my parent's house, I asked my husband how my makeup looked, "surprisingly good" he said. It is now 10 hours past application, and similarly to the blinc mascara which I didn't care for, this has the tendency of flaking a bit and there's some black specks underneath my eye (though I'd say this held up pretty well considering all of the crying) This picture was taken about 15 minutes ago.
In closing, I'll continue to use this until it's finished but I'm not sure I'd repurchase.
