This tool comes with two different brushes at either end:

Conceal Brush –
A soft pure synthetic hair makes it easy to apply, buff in and build up liquid, cream and gel textures, without absorbing the product

Buff Brush –
A smooth, pure synthetic hair makes applying liquid, cream and powder textures easy, without absorbing the product. Thanks to its densely bound, small dome shape, it applies contour, highlighter and concealer in a thin, seamless layer and allows precise placement.
