I recommend the Clio Kill Brow Auto Hard Brow for warm undertones.

I have a warm undertone, and I'm currently using Clio eyebrow products! It's the Kill Brow Auto Hard Brow Pencil, and I seriously think it might be the best-selling brow product at Olive Young!! It draws the best and has pretty good staying power!! I'm already on my fourth purchase haha. The regular price is about 20,000 won per pencil, but it's totally worth it. I will definitely buy it again next time.
