What they say:
"This unique three-in-one brush allows for precision application of blush, bronzer and all other multipurpose dusts and loose powders."
I have come to the sad conclusion that this is the worst brush I have ever used! It is very prickly and feels like straw against your skin. It has next to no density whatsoever as it can hardly pick up any product. Whilst washing the brush, red dye came off the bristles :S It lost its shape after washing and the bristles became dry and nasty!!
One positive is that it can be used for highlighting :)
I don't recommend this brush AT ALL and it doesn't even deserve the £1.50 price tag! This has to be the worst brush in the collection.
