Crows Toes Nidavellir is from the 9 Realms collection 2014.
Nidavellir is a duochrome shifting from purple to a dark teal and it has color shifting glitters. It is very opaque in 1 coat, but this is 2 coats and a coat of Seche Vite. 
I bought it from Norway Nails, use the code MARIA10 to get a 10% discount.
