Ideal for blending eye colors, this crease brush has long tapered bristles that are soft to the touch. Its proprietary blend of synthetic fibers was created to function like natural hair. The fibers have ultra-fine waves which create the porosity needed to pick up, hold, and deposit both powder and cream products. Tested and approved by makeup artists and consumers, the consistency, function, and luxurious feel make these fibers the best alternative to natural hair. Vegan-friendly.
