These are kind of like 3D glasses to me.
I just got Zoya Zuza from the Surf collection, and had to use it. I layered it over OPI Red Lights Ahead.... Where? from the Holland collection.
Zuza actually reminds me of Perry the platypus from Phineas and Ferb.
I know this is kinda simple for a first post, but I'll see ya nail fans :)
