OPI Can't Find My Czech-book is one of the few picks I have from the Euro-Centrale collection, I was drawn to it as it reminded me of What's With The Catt-itude from the Shrek collection of a few years ago. There are a couple of others I quite like, but I haven't bought them yet as I'd like to see more swatches.
This soft dusty teal is a very similar shade to my favourite a-england Galahad, I will try to do a comparison post. In the bottle they look to be dupes, on my swatching spoons they don't look so close.
Here's a picture of Galahad taken for the 31 Day Challenge.
