Self-propelling, self-sharpening, brow-defining and now with an updated water-resistant formula and added spoolie. Offers grooming alongside extreme color precision in one dynamic microfine pencil that emulates fine hair-like strokes on brows for a perfected look. Confidently adds what you need: shape, color and/or density. Like a pen, creates its own just-right point for striking arches. Easy to tote around – no sharpener needed.
