[link]They have 12 random samples so you'd be hard pressed to spot repetition and they're incredibly versatile, there's also three versions:
A - Sharp smoke brush
B - Sharper smoke brush
C - Soft smoke brush
It's basically an updated version of my previous Gimp smoke brush, but with higher quality brushes and a greater range. Feel free to link to any paintings you do with them, I'd love to see how they turned out

As with all of my brushes:
