The bristles are quite stiff and dense despite the length, and the surface area of the brush is quite small (diameter is about 2cm). This means that as far as powder contouring is concerned, this brush will make it look patchy and applies a simple stripe - but when applying a cream product, and especially a stick product, it can blend it in a far more accurate manner without washing the product out completely.

It has natural hair fibres I think, it's quite dense and holds its shape. I use it for highlight and sometimes to powder under my eyes. I don't see how you can contour with such a narrow, stiff brush.

Shape was quite right for contouring but this is such a stiff brush that does not move around easily. I do not know for what purpose I can use this brush now.
