One of the best brushes I've ever used, absolutely an essential in any decent collection of brushes! Perfect not only for lining with shadow, but also for blending, shading lids, actually you can do pretty much your whole eye with this little workhorse pretty effectively, and it handles most types of product really effectively. I've used it with powders, pressed powders and emollient/cream based products, all with great results. It's also easy to clean and re-shape. All in all, a really superb brush!!!!!
