Trish's Brush 30 Eye Blending is designed to softly sculpt the eye and seamlessly shade and blend eye colors. Handcrafted for exquisite quality and longevity. Precision-cut for technically perfect results. Brass ferrules. Directions: To blend eye color, sweep the brush over your finished eye look. To shade, sweep the side of the brush into eye color. Tap off excess and test the color on the back of your hand to ensure you have the desired amount of pigment. Place the brush in the crease of the eye and sweep in a windshield wiper motion until color is seamlessly blended.
