2-in-1 Pro Brow Pen: This advanced liquid eyebrow pen features two professional-grade applicators in one versatile tool. One end is engineered with a 4D Brow-Fection Microblading Brush that creates ultra-fine, hair-like strokes while effortlessly filling and shaping brows. The other end includes a 15 ultra-precise detailing brush specifically angled for outlining, arch definition, and micro-detailing-offering unmatched control for both natural and statement brow styles. 4D Brow-Fection Microblading Brush - Realistic Hair Strokes: The specially designed 4D Brow-Fection brush features a flat angled shape with densely clustered fibers to mimic the look of real eyebrow hair. It easily blends pigment, softly fills sparse areas, and adds natural volume with feather-light strokes. Ideal for achieving structured, feathery, and laminated-style brows in seconds. 15 Fine Detailing Brush Precision Redefined: The opposite end includes a 15 finely tapered brush that delivers microblade-like accuracy, perfect for defining arches, sharpening tails, and drawing hair-like strokes with effortless control. Plus, it easily adds natural-looking lower lashes for a wide-eyed effect. Its smudge-resistant, smooth-flowing formula ensures crisp lines and seamless application every time. Waterproof & Long-Lasting Formula - 24H Wear: Features a smudge-proof, transfer-resistant, and water-resistant formula that locks pigment in place all day. Your brows stay perfectly defined through sweat, humidity, and rain - no fading, flaking, or budging.
