There is no finer detail than the 0.01mm diameter brow pen nib on our Brow Pen. The precision is unparalleled, replicating feather-like strokes that blend in seamlessly with real life hair. Special built-in ink flow technology allows for perfectly even colour application. We know full but life-like brows are the aim, and that it’s all in the finer detail. Use the tip of the pen to create hairlike strokes where needed. Using extremely light pressure, gently fill any gaps, following the natural direction of your natural brow.
