The first brush (starting from the left) can be used for bronzer and blusher. I thought the size of this brush was perfect for its job and felt very soft on the face.
The second brush is for applying foundation however some people like to use fluffier brushes to apply their foundation. I thought it applied the foundation well however I was sometimes left with lines from the brush but that could be my technique of applying my make up.
The third brush can be used for precise concealer or lipstick.
The last brush is an overall face powder brush. I thought this was a very soft brush but if I was to buy another powder brush I would go for a slightly bigger one which Real Techniques do.
This set can be bought from Boots for £21.99 however I found the same set for £16.79 on the Feel Unique website.
