8 shades optional: suitable for different eyebrow skin tones. Whether you have brown eyebrows or blonde hair, you can choose the right colour that suits you. Double head: one head is the tiny brush for precise application. The other head is the brush for grooming and shaping. The unique applicator allows colour to be applied directly to the eyebrow hairs for a natural looking finish. It is comfortable to wear. 24 hours: the waterproof formula can define the eyebrows and fill for up to 24 hours. Stay on for a long time and are more durable. Eyebrows full: For those with thin, sparse eyebrows, this unique, botanical formula gives the look of fuller, thicker eyebrows. Easy to use: To fill the eyebrows with colour, brush the brow gel from the arch and reach towards the tail. Then fill it from the front of the brow towards the arch with the remaining product on the brush.
