Artis Elite Mirror Linear 1 in Metallic Silver. Master your makeup application technique with the Linear 1 Brush from Artis. A narrow row of fibers helps to concentrate product in a precise line, such as along the lash line. This patented brush can apply a defined line along the upper lashes, or be tucked into to the lower lash line to smoke out the waterline. It can also be used to fill in and define the brows or to line along the lips with precision.. Artis brushes are made exclusively with CosmeFibre, a revolutionary engineered fiber made specifically for applying cosmetic and makeup products. Designed for use with liquid, powder, and cream products. ATIS-WU9. ELITELINEAR1G2.
