An eyebrow ratio ruler is a professional tool for determining the balanced symmetry of the eyebrows before applying permanent makeup.

The ruler works on the principle of mathematical determination of perfect facial symmetry. It is the so-called golden ratio, which determines the ideal ratio and proportions. The ruler will make it easy to determine the position and shape of the eyebrows. When you have doubts about uniformity and symmetry, this ruler is irreplaceable, as it will always help you achieve the ideal balance of proportions. On the sides of the ruler, there is a gauge with a scale in centimeters. The three arms are flexible and bendable. The fourth arm is removable. You can put the ruler at different angles to create the best eyebrow design. The stainless steel material is resistant and long-lasting.

How to use: Measure the length of the eye with a longer line (the scale is divided into longer and shorter lines). This length is the ideal distance between both eyebrows. The longer line indicates the length of the eyebrow from the beginning to its highest point. The shorter line is the length of the eyebrows from the highest point to its end. This line also represents the distance from the end of the eyebrow to the outer corner of the eye.
