I picked up this 217 blending brush at the MAC store because its firm enough to apply the color as well. Feels like a dream on the eyes too.

For shading or blending of colour or creamy products. This brush has fine, densely packed fibers that are arranged in an oval shape. M·A·C professional brushes are hand-sculpted and assembled using the finest quality materials. They feature birch, linden and ramin wood handles, nickel-plated brass ferrules.

This brush leaves the makeup looking AMAZZING!! I recommend this brush for everyone, it makes me feel like a professional make up artist! Its well worth the price!
