I have bought many polishes that had been sold as faulty, but that was only because of scratches on the lid or bottle - they never had anything wrong with the polish or brushes.
I have saved one of the brushes by using a cuticle clipper to snip the wonky or too long hairs, so they didn't mess up my manicure, but that was when I started actually noticing the weird brushes. It has made me check all my OPIs to find the bad ones.
Here are the ones with the bad brushes:
Chiffon My Mind
I Cannoli Wear OPI
Give Me Space
In The Clouds
The Sky's My Limit
In My Back Pocket

Show Me Your Tips
|This is the one, where I snipped off some VERY wonky hairs.|
P.S.: Sorry for the weirdly sized photos, I just used the ones showing off the faults.
