This is Jess - Disco Diva.
Jess seems to be a Poundland brand but I've got to say they're pretty darn good!
I'm also wearing purple Allure press-ons from Poundland).
This is a fairly dense glitter, the glitters are all one size and although I've got a purple base it would be possible to build up the layers to make it opaque. There are purple and blue glitters in this mix.
This was only 2 coats.
For £1 you cannot fault this polish.
