오토펜슬이 편리하고 좋죠
What I consider the most important thing is
There shouldn't be any clumping when drawing.
However, I noticed some clumping when drawing with the wooden pencil (this is just my personal experience).
So I'm using an automatic pencil. It doesn't draw too dark lines.
It looks natural.
It is also convenient that the lead keeps coming out just by turning it.
