The Perfect (effortless!) Lash Brush! Featuring an innovative, high-tech rubber (hytrel) brush for effortless application, precision and control without clumping. Lashes look longer and super smooth. The brush allows you to reach smaller lashes at the inner corner of the eyes (and the ones you did not know you had!) with accuracy and comb through your longer, more prominent lashes all at once. The flexible bristles, of different lengths, capture the lashes from root to tip and allow you to hold the lashes in place whilst the mascara sets.
