The E20S Short Shader Brush features a synthetic, short, rounded brush head. It's ideal for adding color to the lash lines or to the outer corners of the eye and anywhere that needs a small amount of concentrated color. The brush is made with SigmaTech fibers, which are synthetically engineered to outperform traditional animal hair. They feature technologically advanced filaments with specialized tips developed to hold and deliver cream and powder products without any absorption into the bristles. Built to last, the fibers are hypoallergenic, antibacterial and will maintain their original shape and color even after several washes. The brush handle is made from lightweight, sustainably sourced wood that is durable and scratch-resistant. Brand: Sigma. Style Name: Sigma E20S Short Shader Brush. Style Number: 5038894.
