I’m a newbie at eyeliner so I was very excited to try this. The pen is quite thick so it’s very easy to grip and is great for beginners like me! I got the shade deep black and it’s highly pigmented. The brush tip is thin so you can go for different eyeliner looks. Also, it is waterproof as it says but you can easily remove it with an oil-based makeup remover. With all this being said, I still suck at eyeliner because my hands are so shaky! Plus, I’ve got half hooded eyes which makes wearing liner such a struggle!
