I'd like a recommendation for really natural-looking eyebrows.

I have a lot of oil around my double eyelids and eyes, so it’s difficult to maintain in the winter, but it’s even harder in the summer. That’s why my makeup usually smudges easily, but this one really lasts. The brown color looks very natural. And did you notice one more thing? The pen is very thin. I was really fascinated by it. It seems to be about half the thickness of a regular pencil. I use it on my eyebrows and also as an eyeliner, and it works really well as an eyeliner.
