This brush is great for the application of cosmetics and treatment products. It will help spread a smooth, even layer of product for maximum benefits. Synthetic Tacklon brushes work great with creams, oils, and liquids. They will spread concealer without pulling or stretching the skin.  The smaller liners or square head versions are ideal for lining the eyes and painting faux hairs on the brown. Taklon brushes are firm, durable and have great control.
