Easy to Use: Both beginners and professionals love our eyebrow pen for its ease of use. The mechanical, retractable pencil features a 0.5mm tip that expertly draws tiny brow hairs and fills in sparse areas and gaps | Features: Our eyebrow pencil has a dual-ended design. One side has a flat tip for outlining and filling in detailed brows, while the other side is a flexible spoolie brush for blending and achieving a seamless, natural look | Waterproof for at Least 8 Hours: The long-lasting formula ensures your makeup stays put for at least 8 hours without smudging or fading, even through sweat, rain, and water sports. It can be easily removed with makeup remover or an oil cleanser | Pro Tip: For more precisely shaped brows, first dot the start, arch, and end of your brow, then connect the dots. Use the brush to blend as needed. This will perfectly frame your face for any makeup look | Eyebrow Razor: Included with the eyebrow pencil is an eyebrow razor for achieving flawless brows. Please use it carefully and keep it out of reach of children
