NYX Epic Ink is my holy grail eyeliner at an unbeatable price. The felt tip is firm and precise, making it easy to create sharp wings or thin lines. The formula is intensely pigmented — one swipe delivers jet-black color. It's completely waterproof and lasts all day without fading, flaking, or smudging. I've worn it through workouts and tears with no budging. The pen format is easy to control and the ink flows consistently without skipping. It removes easily with oil-based makeup remover. At under $10, this performs better than many high-end liners I've tried. The only issue is the tip can fray after a few months, but for the price, I just replace it. This is perfect for everyday wear or dramatic winged liner. My wings have never looked better.
