Review (4/5): Works great after the first week or two
I've used this eyebrow pen every day for the past 12 days and really like it. When I first started using it, though, the ink came out so heavily that my eyebrows looked really dark and fake, and I couldn't get it to look natural no matter how lightly I pressed it. After almost 2 weeks, the ink is coming out more and more naturally and I now have more control over how dark I want my eyebrows to be. So if you want more pronounced eyebrows, you can achieve that look with this pen, and if you want darker but natural-looking eyebrows, you'll likely be able to achieve that look after a week or two.
