The MARS Liquid Pen Eyeliner is a high-quality eyeliner that allows you to create precise and even lines for your desired look. Its felt tip design allows for easy application, including the creation of perfect winged eyeliner. The formula is long-lasting, non-cracking, waterproof, and smudge-proof, ensuring that your eyeliner stays in place throughout the day. The eyeliner is jet black in color and dries to a matte finish. Additionally, the felt tip allows for adjusting the thickness of the eyeliner by applying more or less pressure, and it does not bleed into the fine lines of the eyes.
