Using this eyebrow pencil is a breeze. First, turn the rotating round bead to select the color you want. Then, gently draw along your natural eyebrow line to fill in any sparse areas. Make short, light strokes to mimic real hair for a more natural look. When you're done, use the spoolie on the other end to blend the color evenly. As for maintenance, keep it in a cool and dry place. Avoid dropping it, as this could damage the rotating mechanism. If it gets dirty, you can wipe it with a clean, dry cloth. Also, be careful not to expose it to extreme temperatures, as this may affect the quality of the pencil lead.
