The Saem Eco Soul Mega Slim Waterproof Eyeliner – Deep Black 1.5mm

Achieve sharp, smudge-proof definition with the Eco Soul Powerproof Mega Slim Liner in Deep Black, a long-lasting Korean eyeliner designed for precision and all-day wear. Featuring a remarkably fine 1.5 mm mega-slim tip, this liner allows you to create crisp wings, tightlining, or ultra-thin natural lines with complete control. Its sleek formula glides effortlessly without skipping, tugging, or fading.

The deep, rich black pigment delivers instant intensity, helping you enhance your eye shape with bold color payoff from the very first stroke. Whether you prefer a natural everyday look or dramatic, graphic lines, this eyeliner adapts to your style while keeping the finish sharp and defined.

Built with a powerproof technology, the formula is fully waterproof, sweat-proof, and smudge-proof, making it ideal for long days, humid weather, workouts, or tear-prone eyes. It resists oil, moisture, and humidity to ensure your eye makeup stays intact from morning until night without flaking or transferring.

The ultra-thin tip makes it beginner-friendly and perfect for detailed work, tightlining the lash line, or creating layered makeup looks. Its lightweight texture sets quickly and stays comfortably in place without cracking.

Suitable for all skin types, the Mega Slim Liner provides a clean application that doesn’t irritate the delicate eye area. The compact design makes it easy to carry in your makeup bag for touch-ups—though thanks to its long-lasting hold, you’ll rarely need them.
