This is such a beautiful duochrome, I thought it deserved three photographs to show you :)
This is three coats of Rainbow Pink. Application was very nice, but it takes forever to try by itself and is a little bubble prone if you aren't careful.
I found this at one of the many dollar stores in my hometown, a bargain at $3. I may need to check out there collection again shortly. The owners daughter picks out all the good ones for herself before they get sold, cheeky little hua. I guess she is a nail polish lover too :)
