I also found this polish in my stash, but I forgot I got it in 2015 from the KBShimmer Winter/Holiday collection. Claws and Effect is a dark purple-leaning navy holo polish with blue/pink shifting glass flakes. I originally thought it was a straight holographic purple polish!
I started with cuccio Base Coat, 2 coats of polish, and finished with cuccio High Gloss top coat. This polish applied really well!
The blue shifting glass flakes were the prominent winners here. However, I could only see the holo under a harsh light. While it's pretty, this polish is not for me and I'm looking for it to go to a new home.
This polish has been discontinued.
