Because of the formula’s fluidity, it blends exceptionally well. This shade has a very slight shimmer to it (grr!), but is pretty much as good as blush gets other than that.
So, what you need to know is that if you buy the blush, a donation from each sale of Charm goes to the Moon and Stars Charity raising funds for Cancer Research UK, you get the brush completely free. Given that I am forever banging on about how it is my best ever brush for blusher (I have three!), I can only urge you to buy the Charm Watercolour whether you like it or not! I actually had to double check this but yes, the brush is free.
