번짐이 적다니 좋네요
It is the Etude House Proof 10 Waterproof Pencil.
This product used to be famous a long time ago, but now it has been renewed and is being released as a gel waterproof pencil.
But since I bought several of these when I purchased this product before, I am still using them well.
It draws smoothly and easily, and seems to smudge minimally.
