My base polish for this mani is Picture Polish Pshiiit, a duochrome shimmer shifting from green to teal, with some flakies in it. I used three coats for opacity.
For the stamping I used Kiko Mirror Lacquer 625 (Emerald) and, ah well, some stamping plate. I usually put the plate away until I've written the blog post, but apparently I forgot this time, so I honestly don't remember which one it was, sorry!
Picture Polish are available at Harlow & Co., Pshiiit and their own shop (plus many more, here's a list of additional retailers).
