I love the convenience of Nicka K Eye Light Crayon, on days when I do not feel like doing a whole lot with my eyes this product comes in handy, so I always have it in my makeup bag. They are easy to use, they guide on easily, stays on long, and are very pigmented. The only thing is I find on my eyes they can crease but I have hooded eyes. I want to buy all the colors in this line, and I have recommended these crayons to many friends.
