I've had this brush set for a while now and finally feel like I can do a proper review of these brushes.
Packaging: Brushes comes with a little hemp bag, however I feel the bag is too smal to fit all the brushes.
The set includes mineral powder brush, a mini kabuki, a concealer brush and an eye shading brush. They are super soft, they don't shed and they feel good in my hand. Here is what I think about each individual brush:
Mini Kabuki: I don't really use Kabuki's so I have not been reaching for this. It's not a bad brush at all I just have other types of brushes that I prefer to use. Maybe I would use this for bronzer, but the bronzer I have right now is quite dark and needs to be applied with a stippling brush to not look too overdone.
Concealer brush: Very nice brush, I use this every day. I don't know how I ever managed without a concealer brush.
Eye shading brush: this brush is quite large, so I use it as a blending brush, and I absolutely love it for that purpose! This is by far the best blending brush I have ever tried.
Powder brush: I have not been using this very much. I feel like it's not dense enough for a powder brush ( I prefer elf's flat top brush) It is nice for a natural blush application however it is a bit big for my face. So not a bad brush at all, I just don't really know what to use it for.
I will certainly recommend these brushes, if you know what typeof brush you are looking for to do a specific job, you won't be disappointed to try Ecotools out.
