I really like this Flat brush from MUFE, but I just do not used it as a highlighter brush but as contouring brush. It is perfect, I have small features and have to be careful with placement and this brush really do the job. Small, take just enough product and dust lightly the face, I can contour the hollow of my cheeks and the side of my nose. It is super soft and easy to clean.
This is a nice multitasking brush. It was made for highlighting the facial features but since it's medium sized not-too-fluffy brush it can be used for anything. I bought it for applying one light shade all over my eyelids and this does the job perfectly. It's very soft and gentle just like the rest of this range. Although it feels soft as silk it grabs a good amount of product.
It's great for its intended purpose as well, just the right size for upper cheekbones. Flat shape makes it easy to highlight the bridge of nose.
This can also be used for applying cream/powder concealer to areas like nostrils and under eyes.
Because it's synthetic it didn't shed a single strand and it's not high maintenance like natural ones (which you would need to condition after every wash to prevent shedding and maintain the softness) It also does not need reshaping, synthetic hair maintains its shape unless you throw it into the fire :) Synthetic also means cruelty-free so that's another bonus.
If you like to use one brush for multiple purposes, check this one out :)
