I bought this after seeing a professional expert use it... I usually use the Hwahang 982? The green one, but I was curious so I tried this. My usual use is for covering dark circle lines. This brush is a bit bigger, so it seems okay for covering overall color correction. However, it’s hard to do delicate touch-ups. If you have particularly dark circles like me, unless you’re a true expert or pro, it’s quite difficult to cover well. I think I’ll use it if I have it, but it’s not a must-have for covering dark circles. Some bristle splitting, but that’s common with most concealer brushes. You have to break it in well, but I was too lazy to do that and left it as is. Even left unattended, it didn’t split that badly. When you tap it gently, the edges blend well.
