Mac cosmetics 189 brush New with packaging Discontinued Bundle and save flat, paddle-shaped brush with rounded edges. It is made out of synthetic fibres, which makes it good for both powder and more emollient products. This was originally launched with Mineralize Skinfinish Natural. I really like this brush for applying pressed powders to the face, and I also like it when applying creamy products like a moisturizer or a cream blush as more of a highlighter or if I want more precision.
