This is Le Beau's 4mm eyeliner brush. It features a wooden handle and synthetic bristles. It has just the right amount of elasticity and applies lightly and thinly—it's a real gem. Its straight shape makes it perfect for detailed eye makeup. At 6,000 won, it isn't too expensive, yet the quality is excellent. It's easy to handle, and it has become my absolute holy grail. When you apply eyeliner with it, the lines draw nicely without looking too thick. If you use liquid or gel eyeliner, you'll likely need an eyeliner brush, so give this one a try.
