I Don't Think So Get In Line Brush Pen Eyeliner 1ml

A flexible brush pen that lets even beginners draw seamless lines

The 0.01 mm ultra-fine brush pen glides effortlessly between lashes and along the lash line, filling in every gap with precision. Its springy bristles respond to pressure, so you can create anything from a slim, delicate line to a bold, dramatic stroke. The forgiving structure makes it easy for shaky-handed beginners to achieve a smooth, even line in one go.

Film-coating formula that lasts from morning to night

The waterproof film-coating formula resists water, sweat, and oil without smudging. Your line stays sharp and defined all day long, yet washes off gently with a foam cleanser—no tugging on the delicate eye area. Give it a light shake before use to keep the color payoff vivid down to the very last drop.

Two shades for every mood: everyday Brown and deep Black

Black: A crisp, defined line that adds striking presence to your eyes
Brown: A soft, muted depth that complements natural, everyday makeup

Reach for Brown when you want a subtle, understated look, or choose Black on days you're after a more defined, impactful finish.

After eyeshadow, before mascara

Apply your eyeliner after you've finished your base makeup and eyeshadow. Following up with mascara will give your eyes even more definition. For longer-lasting wear, lightly dust the eye area with powder or shadow before lining to absorb any oils or moisture.

Draw freely with the flexible brush pen

Before use, hold the pen with the brush tip facing downward and shake gently to mix the ink. The springy brush tip lets you create everything from delicate lines that fill in between lashes to bold, elongated flicks at the outer corner. If you're new to liner, try building the line in short, connected strokes.

How to style each shade

• Dark Brown: Perfect for everyday makeup. Creates a naturally defined, softly intense look.
• Black: Ideal for important occasions like interviews or presentations when you want a sharp, striking impression.

What to pair it with

Dark Brown pairs beautifully with beige or coral-toned eyeshadows. When using Black to define your eyes, a nude shadow base will make the liner stand out even more. Layer with a waterproof mascara for smudge-proof eye makeup that lasts all day.

Removal and storage tips

The film-coating formula dissolves easily with a gentle cleanser or lukewarm water. Avoid rubbing harshly—gently wipe the eye area instead. If foundation or other products get on the brush tip, the ink may not flow properly, so wipe it clean before use. Store away from direct sunlight and use within 12 months of opening.
