Sharp lines that don’t smudge
Color: Black, Size: 0.01 Ounce (Pack of 2)
This eyeliner is very precise and easy to apply, allowing you to create clean, sharp lines without much effort. The waterproof formula holds up well throughout the day without smudging or fading easily. It works well for both subtle everyday looks and more dramatic winged eyeliner styles. The built-in sharpener also helps maintain precision over time. Overall, it’s a dependable eyeliner for long-lasting eye definition.

Revlon colorstay pencil
Color: Sapphire, Size: 0.01 Ounce (Pack of 1)
This liner goes on well and has staying power. I like the color and am happy with this purchase, however… it needs to be sharpened just about every use. I probably won’t order again.
