If you take out too much of the contents, it won't go back in and will break.
I was worried because the reviews said it breaks easily, but I got the hang of it after using it for a while. If I twist it just a tiny bit, it draws a thin, clean line without smudging, and the staying power is decent, so I'm using it almost to the end. I tend to use cosmetics for a long time, so I feel like the amount inside is a bit small.
I like that it draws thinly and the color is natural and not too intense.
