I have used the Egyptian Clay smudgestick for years as a brow pencil. It is the perfect color for those of us that have dark, dark brown to black hair. Usually products that are designed specifically for brows is either too light, too red or too gray for me to use on my brows. The color was always "off" but not with the Skinn Smudgestick and it stays put allday even on my oil skin. I apply it using a slanted brush and the results are perfect brows every time.
Does exactly what is promised. Waterproof, smooth and easy to apply and lasts for ages. Comes in some great colours. I have the Egyptian Clay, which I use as both an eyeliner and eyebrow pencil. Would repurchase :)
