These pencils are smooth and  pigmented and they don't skip on the skin. These professional grade pencils sharpen to a fine point without crumbling to create the outline to your brow and even draw hairlike strokes. This formula can be used 7- 10 days after microblading to get your through the "ghost phase" This is the phase where 7-10 days later freshly microbladed brows seem to be fading away. This is temporary. Once the skin fully heals and they "reappear"  you can use the pencil as a liner or to create a more dramatic effect for special occasions.
