Kiss Me Heroine Make Prime Eyeliner

As an autumn warm tone, I use brown eyeliner because black doesn't suit me well. I am currently using the Kiss Me Heroine Make Prime Eyeliner in brown, which I purchased at Olive Young. The brush is thin, so it glides on smoothly, and since it is waterproof, it doesn't smudge easily. However, because the brush is so thin, it is a bit difficult to apply. I recommend this to those who prefer this type of thin brush.
