Each brush in this set of four is shaped differently. I tend to use the angled one for blending out concealer, as the sharp point can fit around tricky areas like the nose and under the eyes. I like the domed brush for applying cream eyeshadows all over the lid, and the pointed brush is great for applying colours in the crease, when you don't need to be too precise. My favourite brush however, is the flat topped one. I use this for patting and swirling on cream blush products.
I like these brushes and will continue to use them. They're not the greatest makeup brushes in the world, no, but they get the job done nicely. I also think they look very sleek, and the bristles are soft and dense. They also clean well with no bristle fall out, which I know can be an issue with cheap brushes. All in all, I'd recommend you give these a look if you don't want to spend a lot on makeup brushes, as the set is less than £3!
