Key Features and Claims:

Intense Black Color: The eyeliner is known for its highly pigmented, rich, and deep black shade. The name "Darkside" emphasizes the intensity of the color, which is designed to add drama and definition to the eyes.

Waterproof and Smudge-Proof: A primary feature of this eyeliner is its waterproof and smudge-proof formula. This makes it ideal for creating long-lasting eye looks that can withstand humidity, sweat, or watery eyes without smudging or running.

Smooth and Creamy Texture: The pencil is formulated with a creamy texture that allows for a smooth, effortless glide. This prevents tugging or pulling on the delicate skin around the eyes during application.

Versatile Application: The pencil format is versatile, allowing for various eye makeup looks. It can be used to create a classic, thin line along the lash line, a bold winged look, or a smoky eye effect. It's also suitable for use on the waterline as a kajal pencil.

Suitable for Sensitive Eyes: Some product descriptions mention that the formula is gentle and suitable for individuals with sensitive eyes and those who wear contact lenses.

Long-Lasting Wear: The eyeliner is designed to stay in place for an extended period, making it suitable for all-day wear.
