I recommend the Tony Moly Easy Touch Auto Eyebrow.

I have been using Tony Moly eye makeup products for a long time because I often received recommendations for them. Although I am a Summer Cool tone, I don't necessarily try to stick to products on the Summer Cool color chart; I just choose whatever looks like it would suit me. Brown is natural and nice, but since I have fairly thick eyebrows, I prefer black shades over brown. However, I don't prefer products that are too intensely black; I prefer a subtle black like this. Should I call it a charcoal feel? It seems to suit me well and is not overwhelming.
