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. It can also be referred to as all in one makeup brush, alleyoop 4 in 1 makeup brush or physicians formula 4 in 1 brush.
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.
