I bumped into this brush due to economic factors a couple of months ago. I was desperate for a full coverage brush and found this lovely one: Everyday Minerals Bamboo Long Handled Kabuki Brush
It was a super good price, around 13 bucks and I didn't expect it to last long - just until I could afford one of the more expensive brushes I have become accustomed to.
It has lasted over six months of daily foundation application use. It washes out nicely, applies bronzer, mineral makeup and copious amounts of blush really well.
A whole set of brushes for under 10 bucks!
If you have PRIME - shipping is free at Amazon!
Just in case you need it... here is some great brush cleaner:
