I have purchased this brush a couple of days ago and I am so impressed I haven't stopped using it ever since!
The foundation brush (the bigger brush of the two): It has really restored my faith in foundation brushes! I have tried it with both liquid and cream foundations and it works equally well. It applies a perfectly thin layer but with enough coverage. The foundation really looks professionally apllied. It is very easy to build up coverage on spots that need it more. It leaves no streaks behind. I have even dug up some foundations that I haven't used in ages because I didn't like the finish they gave. With this brush I have been able to use them with great results. I am really impressed!

The concealer par is also really good. I use it for applying liquid concealer under the eyes and to also dab consealer on blemishes. I find it works better then fingers because fingers often wipe concealer off as you try to smoth it out.

Both brushes are made with nylon hair. They don't seem to shed at all and clean out easily.

I really recommend it! I hope it works as well for others!
