Overall this set of brushes is pretty awesome!
Detailer Brush - it's intended use for concealer is ok, I actually use it for lipstick application and sometimes smudging out eyeliner.
Pointed Foundation Brush - It's a little time consuming & tricky getting a perfect application of foundation. I only use this for parts of applying foundation, mostly under the eye and to get around the nose. It is very handy though for applying concealer under the eye.
Buffing Brush - This is a multipurpose brush for flawless application of mineral powder and liquid foundation. It's also really great for creating a very natural blushed cheek powder or liquid.
Contour brush - Great for precision in applying bronzer or blush to your cheeks. I have sometimes used it for spot powdering my face.
All brushes are synthetic and are super easy to spot clean. They all hold any product nicely and you can use all brushes for powder or liquid. Even though I'm not using all the brushes for their intended use I am super stoked that I have found other uses for them!
The case that these brushes come in is very versatile! It's also great for protecting your brushes for travelling and super awesome for drying your brushes as well after a deep clean!
I love that these are affordable, available online for international buyers and that the creator has tutorials on all of the brushes - which is hugely assuring and encouraging!
