This product is great. I used the entire tube. It fills and combs brows at the same time. The dark brown shade was perfect , I could do 1 swipe for a natural effect or build it up if I needed to go darker. My only issue with this type of product is that I needed to use it with a pencil to fill out the very light parts of my brow where there is barely any hair. When Im in a hurry its just easier to use a pencil only to do a similar job.
