This brush is perfect for blending your eye shadows.  We searched high and low to bring you a brush that has just the right amount of synthetic hair to blend perfectly.  During our search the brushes we found were either too short or too long.  This brush is just perfect!  This brush is made of synthetic fibers.  Synthetic fibers are the best for applying cosmetics as they hold up to the rigorous tasks of wet applications and don't fall apart when you wash them.  Hair brushes are, well, hair!  They split, break off, become dry, and do not give the superior wet application that you will get with a synthetic brush.  And, all the little animals get to keep their hair.
