Cheolbyeok Pen Liner

8-Hour Ultra Long-Wear Eyeliner

A fitting polymer technology locks color onto skin while forming a protective film on the surface that shields against sweat, oil, and moisture. The line you draw in the morning stays sharp and intact until cleansing. The power-coating film resists smudging from friction and sebum, keeping your eye look crisp all day long.

Flexible, Resilient Brush for One-Stroke Precision

The soft yet springy brush glides seamlessly along the lash line without skipping. From delicate flicks to tight-lining the waterline, it offers full control—making it beginner-friendly. Shake gently 2–3 times before use to ensure even ink flow and enjoy fresh, vivid color payoff every time.

Two Sophisticated Shades to Set the Mood

• Deep Black: A true, neutral black with no blue undertones—creates depth and intensity like a black hole
• Deep Brown: An authentic brown free of red tones—delivers a soft, sultry look

Reach for Deep Black when you want bold definition, or choose Deep Brown for effortless everyday wear. Rolls off cleanly with lukewarm water, so it's gentle on the delicate eye area.

After eyeshadow, before mascara

Complete your base makeup and eyeshadow first, then apply your eyeliner. Finish with mascara after lining to define your eyes even more.

Shake-to-activate pen format

Gently shake 2–3 times before use to mix the formula. Use the flexible brush tip to dot along the lash line, filling in between lashes, then connect the dots into a seamless line for a natural finish. For the outer corner, follow your natural eye shape and flick slightly outward for a clean look.

Liner looks for every occasion

• Office: Use Deep Brown to thinly fill the lash line for a polished, understated look
• Everyday: Use Deep Black with a subtle lift at the outer corner for definition without drama
• Evening: Use Black to extend the outer corner and layer with eyeshadow for added depth

Pairings that work

Deep Black pairs beautifully with brick-toned eyeshadow for dimensional depth. Deep Brown complements rosy shades for a soft, sultry vibe.

Care tips for longer use

Store horizontally to keep the brush tip from drying out. To cleanse, gently roll the tip under lukewarm water. Use within 6 months of opening, and discontinue if any irritation occurs around the eye area.
