So the COLOR MASTER Eyeliner 01 in Extra Black is honestly a game-changer. It's got this super thin tip that's made in Italy, and let me tell you—it makes drawing that perfect line way easier than you'd think. Whether you're going for a clean everyday look or something more dramatic, this thing just glides on without any dragging or messiness.What I really love is how waterproof it is. Like, it actually stays put all day without smudging or fading, which is clutch if you've got a long day ahead. The black is seriously intense too—none of that wishy-washy gray stuff you sometimes get with cheaper liners. It just makes your eyes pop and gives you that sharp, defined look that pulls everything together. Pretty much perfect if you want your eye makeup to actually last and look good doing it.
