Revlon ColorStay Micro Hyper Precision Gel Eyeliner in the shade "Black" is a long-wearing, waterproof eyeliner that delivers bold, precise lines with ease. The unique gel formula is designed to glide on smoothly without smudging or smearing, and the ultra-fine tip allows for precise application. The ColorStay Micro Hyper Precision Gel Eyeliner is also transfer-proof, meaning it won't smudge or transfer onto your eyelids throughout the day. It is also water-resistant, making it perfect for hot or humid weather, or for long days where you need your makeup to last. To use, simply twist the pencil to expose a small amount of the gel liner. Use the ultra-fine tip to draw a thin line along your lash line, or use the side of the tip to create a thicker line. You can also use the liner to create a winged or cat-eye look by extending the line outwards at the corner of your eye. The "Black" shade is a classic, intense black that is perfect for creating a dramatic, bold look. The precision and staying power of the formula make it a great option for any occasion, whether you're heading to work or out for a night on the town.
