Fan out lashes side-to-side, amplify volume, and multiply the look of lashes for an instant eye-opening effect. The custom-engineered Full-Flex Fiber Brush has a 40 curve that lifts root-to-tip and reaches corner-to-corner. It features naturally derived flex-wave fibers that grab, define and separate lashes, cleanly and evenly. Plus, the fanning formula is buildable, feels weightless and doesn't clump or flake.
