I don't know if Eyeko are even selling Disco Polish anymore but, hot damn, they should be.
This is one of the best glitter polishes I've come across. Two coats and it's done. And, seriously, isn't that one of the nicest glitters you've seen!
This does dry to a rough finish so you will need Seche Vite to smooth it out. Oh, and it's an absolute pain in the a** to remove but, then, aren't all dense glitters?
For under $5, this is a worthy investment if you can still find it.
