2 Brushes, 2 Formulas! Featuring two mascaras in one dual-ended pack, these ultra-black formulas are clinically proven to volumize, lengthen, lift, and curl lashes. Surprise Your Eyes Mascara glides smoothly onto lashes for an even, buildable, and clump-free application. Side Volumizing: Short, volumizing fibers give an extreme volumizing effect for fuller, thicker lashes in just a few strokes. Side Lengthening: lengthening fibers give an immediate elongated effect while the brush curls and lengthens even the tiniest of lashes for a fluttery effect.
