Oh, Birchbox. You've sent me five mascaras in about as many months. But I think this one is my favorite (followed closely by Benefit's mascaras). I like super full lashes, and this does the trick marvelously. Really good for extending the wing at the outer edge of your eye--you can layer it on without it getting too clumpy. But not for ladies who like super defined, separated lashes. This will just give you a gorgeous sweep of dark. Good for bottom lashes as well, which is hard to find.
