No need to waste time in measuring if your eyebrows are on the same shape and size as the stamp does the job for you. Each set of eyebrow powder has an ombre color combination for more blended and nature-looking brows. It is perfect for all brow shape and types as you can adjust the arch depending on your shape. Just put on eyebrow powder to the stamp and stamp it to your eyebrows. The formulation is safe on the skin as it is alcohol-free and latex-free.
