The F05 Small Contour Brush by Sigma features a small, dense, rounded brush head. It's best for contouring the cheekbones with powder products using a buffing, circular motion to blend contour shades. The brush features SigmaTech® fibers, which are synthetically engineered to outperform traditional animal hair. The technologically advanced filaments with specialized tips are 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.
