Quo Beauty Lash Adhesive Liner is a 2-in-1 product that functions as both a black liquid eyeliner and a lash glue. Its precision felt tip applicator allows for a clean, simple stroke along the lash line, providing an adhesive base for false lashes. This vegan and cruelty-free formula is designed for easy and effortless application. For best results, shake well, apply an even layer to the eyelid, wait a few seconds for it to become tacky, and then press your favorite false lash onto the liner.
