you know the right brushes can make all the difference. And the UD Pro Optical Blurring Brush by Urban Decay is the ultimate blend of form and function. The densely packed shape distributes foundation evenly, buffing to a natural, soft-focus, airbrushed finish. It s also great for contouring, blush, or anything that needs a blurred-out effect.Urban Decay's pro-quality, cruelty-free brushes are easy on the eyes and the environment. The brushed gunmetal handles are made from recycled aluminum, and the super-soft, synthetic hair (made from recycled plastic bottles) mimics real hair-from the feel to the pickup and laydown. Another plus: Synthetic brush hair doesn't hold on to gross bacteria the way porous animal hair can, so it's easier to clean and more hygienic.
