The most commonly used eyebrow pencil products are paper refills, wooden pencil-type or mechanical pencil-type eyebrow pencils. The eyebrow pencil refill is composed of pigment dispersed in low melting oil and wax base, kneaded, and then made into a core. The color of the eyebrow pencil is brown, black, and gray. Depending on the skin color, you can choose different shades.
