If you're on Facebook, check out China Glaze's page for pics of the Wizard of Ooh Ahz Returns collection, including swatches.
Here's the whole collection (which apparently ships this month) to get you started:
Left to right: Ruby Pumps, Cowardly Lyin, The Ten Man, Dorothy Who?, C-C-Courage and Good Witch.
Will you be getting this my pretties? I think I will, although I will then have three bottles of Ruby Pumps! Worth it I think, because I'm coveting Dorothy Who?, C-C-Courage, The Ten Man and Cowardly Lyin.
