The Dark Defender is the name of today's polish, and it's by Cadillaquer.
The Dark Defender has a dark teal jelly base filled with tiny blue, green and purple flakies. I used three coats for opacity and added one coat of Pahlish Magic Mirror Top Coat.
Cadillacquer polishes are available at Hypnotic Polish and at Harlow & Co. If you live in Switzerland you can also order the polishes directly from Madeleine (Miss Cadillacquer herself) via Email on her Blog.
