I have heard a lot of great reviews on these brushes from Sigma. It's the angled top kabuki brush that's perfect for application on cheeks both using powder, creams and liquids. The flat top kabuki brush which is used to apply foundation in liquid or powder form and the round top kabuki brush that can be used under the eyes and around the nose.
The brushes should make your makeup look flawless and airbrushed. I'm buying some myself after all the great things I've heard about these brushes. There's always a lot of reviews on Sigma's brushes and they are all good so it's time to try some myself. Click on the link in the sidebar to look through their range of brushes.
