What it is: A liquid eyeliner pen, with a precision brush tip, that wears strong all day long. What it does: Add a painterly touch to your eyeliner application. Brushstroke Liner features a precision brush tip that makes liquid lining sharp, fast, and easy. This mistake-proof, tapered-tip pen creates the perfect line—thick or thin—in one sweep. For the finest line, use the brush tip. For a bolder one, try the brush’s flat side. Smudge-proof and budge-resistant, this liner offers superior, intense color that wears for up to 24 hours, yet removes easily with just warm water. This formula is transfer-resistant, water-resistant, and sweat- and humidity-proof. It is ophthalmologist-tested, and safe for contact lens wearers.
