Beauty Strokes - Brushes

Has anyone heard of BeautyStrokes brushes before?

I'd like to try the following.

• Blusher Brush
  
• Face Powder Brush
• Bronzer Brush
• Crease Brush (especially)
  

The bristles are made out of natural hair. I'd imagine that they'd be very soft. I'm curious to find what you all think of these.
