I have tried this product in the color "Dark blonde". The color is quite dark, so my recommendation is to rather choose a lighter than a darker shade if you feel unsure!
The brush has very high precision! It is very thin and has two small brush tips. The consistency of the product is like a liquid eyeliner. When you paint, it creates two hair-like strokes at a time! If you want to draw one line at a time, you can angle the pen/brush the other way!
I have quite sparse brows, so this technique of mimicking brow hairs rather than filling in the brow with a color works very well for me! It looks very natural!
You have to be a bit careful and light-handed; if you apply too much, it’s hard to remove, the product stays on very well. The first few times before I learned the technique and got familiar with the applicator, I had to start over a couple of times, I applied too much! But after a few uses, I know how much/little is needed for a good and natural result!
It's nice not to have to sharpen a pencil, and the result lasts long!
The review was conducted on behalf of Smartson - the test pilot was allowed to try the product for free.
