Kristi is part of the Wonderful Collection for fall 2010 by Zoya.
It’s a bit sheer, so I had to apply 3 coats to reach opacity. The formula is quite runny and can be a bit tricky to deal with.
It wears better than Sam, though. I have it on my nails for 3 days and there’s no chip wear.
I’ve bought Kristi by Zoya on Zoya’s website and got a BOGOF, so it only cost me $4 :)
