Baby Bright Up and Down Duo Eyeliner is a convenient 2-in-1 tool that delivers jet-black color with precision. The upper-eye line is drawn with a 0.05 mm felt-tip for a crisp, clean stroke, while the lower line uses a smooth 2 mm gel pencil for a natural definition. Waterproof, sweatproof, and smudge-proof to stay put from day to night, it’s enriched with macadamia nut oil to nourish the delicate eye area. How to use: 1) Uncap the felt-tip side and draw along the upper lash line. 2) Uncap the gel side, twist up, and apply along the lower lash line or waterline. Close the cap after use.
