This is a light green-silver duochrome (and a very shy lavender shift) with silver shimmer. It’s a hard polish to photograph but it’s very pretty and shiny, and makes me think of fishscales. It’s part of the Katy Perry collaboration with OPI and you can see her fun fashion-touch in the collection.
Now on the much less exciting side, the formula is not at all fun. It’s thin and brushstroke-y. I can’t get a decent picture of the colour shifts as I have bald spots on the longer nails with 2 thick coats. I might try it with a black undercoat but it’s really not great for the OPI price tag. And the wear is not good, I have light scratches even with two layers of top coat and it’s really obvious with this sort of finish.
