I think there are, like, 30+ mascaras in my drawer, but I keep going back to this one. It’s the Estée Lauder Double Wear Zero-Smudge Lengthening Mascara.
I use it mainly for my bottom lashes, but I love it too when I want decent, but full lashes. The brush is perfect, the formula doesn’t clump, dry out too fast, as is a true black. Can be applied in several layers.
