This is the Ansi Brush Cream Cheek & Primer Brush Ebony 11. Cream Cheek & Primer Brush Hair Material: High-grade synthetic hair Handle Material: Walnut wood Size: Overall length: 190mm, Bristle length: 32mm [From the website] "You use a brush for primer!?" This is a must-have brush for you. Because using a brush for base makeup will dramatically increase the staying power of your makeup by 3 times! The thin, wide shape is the secret to allowing anyone to easily apply the product evenly. By adhering thinly and closely to the skin, the foundation applied afterward will fit better and be less likely to smudge. It can also be used to apply sunscreen, which tends to make your hands sticky. In addition, because the tip of the brush is designed to be pointed, it is also excellent for applying and blending cream blush as desired. This brush will be a triple threat.
