Long wear volumizing mascara

Said to be worn by Cleopatra for its protective features, the Onyx stone packs beauty solid as a rock. This mascara will make your lashes reach high, pulling everybody near you into the deep grace of your eyes.

Enriched with powerful active ingredients, the Onyx Lash Booster Mascara will make your lashes appear longer, stronger and healthier over time. And its double tapered brush covers every single hair, from bottom to tip, for extraordinary volume and definition. Clumps and empty spaces are histories.


Please note: The overall appearance of the lashes may differ depending on the size and shape of your eyes.
