This is her etsy GlitterDaze. Her shop is at the moment not open but you can follow her on facebook to find out when it will be open next.
Iris is a clear polish with a rainbow set of glitters. I really like all the different colors in it. You can see here how pretty it is over Anise's Sea Siren.
It goes on pretty nice and like all glitter polishes if you want real thick glitter coverage let the first coat dry and then coat it again.
