I recommend the FilliMilli Corrector 811 Brush.

It is a good brush for covering nose pores, butterfly zone, and dark circles.
I mainly use it to cover pores and dark circles, but I also like that when I apply foundation or cushion by patting it on, it feels like the pores are filled in, making the skin texture look even.
Because the bristles are dense and rounded, if you press gently sideways with light pressure, it is good for covering dark circles.

Gently patting it on helps cover pores.
And I think the biggest advantage is the value for money at 8,500 won. I'm not very good at explaining things, but if you search for "FilliMilli 811" on YouTube, a lot of videos come up because many YouTubers use it, so you can watch those for reference.
