The Liquid Foundation Brush is specially designed to deposit the right amount of liquid foundation for a precise, even & smooth application. The bristles are tapered so you can easily customize the level of coverage. Made of synthetic bristles -a good choice for liquid-based products because they hold their shape and don’t expand when wet. Soft-touch foundation brush is oval-shaped to work with the contours of the face, including narrow areas around the nose, mouth, eyes and hairline. New.
