Review (4/5): The pencil is soft and easy to draw with
The pencil is soft and easy to draw with (and wipe off if you've made a mistake). The color is flexible and works for multiple hair colors. It stays on all day and washes off without trouble at night.
However, the sharpening process is a nightmare. Because of the soft nature of the pencil, the sharpener on the back, no matter how carefully and gently you use it, simply breaks off the tip of the pencil and gets it lodged within its blade.
More than 70% of my pencil must have been lost to that sharpener.
