Aritaum Idol Waterproof Eye Pencil

My eyeliner tends to smudge easily, so I bought and am currently using the Aritaum Idol Waterproof Eye Pencil. I used to use a Tony Moly product, but it was inconvenient, so I switched to the pencil type. It applies a bit thickly, but since I only use it occasionally rather than every day, I am satisfied with it. Being a pencil type is really convenient, and it's great for carrying around too.
