The Diorshow Pump 'N' Volume Waterproof Mascara creates instant volume with the simple power of a squeeze. By pumping the soft tube, you generously coat the brush and soften the creamy, rich mascara formula inside for a perfect, fresh application, every time. The special bounce-effect brush features ultra-supple bristles that load lashes in a single sweep, creating daring, pumped-up volume without clumping. This is lash volume pushed to the extreme.
