For maximum coverage: Use fingertip and tap shadow onto eye lid. A flat, fine tip synthetic brush will work fabulously as well and is actually better for a more detailed application close to the lash line. However, your fingertips make for the most intense application. To blend: Use a fluffy brush that has good movement, dip tip of the brush into the shadow and blend with a "wind shield wiper" movement throughout the crease of the eye. This will make your shadow softer and more diffused (like a total pro). When finished, close that sucker up tight! Don't leave the jar opened for long periods of time, you may lose some of the magic that makes the Super Shock Shadow so amazzzing.
