All 4 one and one 4 all! At first glance, this makeup brush appears to be a dual ended blending brush. However, when you slip off the brush tips, you’ll find two additional brushes contained inside. The outer brushes include a blush brush and an angled stipple brush, which is perfect for applying foundation, highlighting or contouring. The inside brushes include an eye shadow crease brush and an eye shadow/concealer brush. All four brushes feature nylon hair.
