## Features

- 3-In-1 Black Lash Primer + Eyeliner + Mascara: This best-selling, all-in-one peptide-infused eyelash primer, eyeliner, and lengthening mascara delivers rich black pigment for bold definition in one step. Ultra-conditioning formula with biotin, peptides, jojoba, aloe and antioxidants nourishes your lashes from root to tip.
- Tightline Eyeliner Effect For A Fuller, Thicker Lash Line: This black mascara primer lengthens and defines lashes as it deposits pigment between every lash for instant tightline eyeliner effect and the appearance of a fuller, thicker lash line.

- Easy, Mess-Free Application: Starting at the root, hold the wand horizontally, wiggle and sweep from base to tip. Fill gaps by pressing along upper lash roots. Wear alone or under mascara, and add additional coats for more drama.
