The other three is some opi mini neons I had given to me by my very sweet friend Sarah.
The yellow is O.P.I - Ridiculously Yellow
The pink is O.P.I - Riotously Pink
The orange is O.P.I - Formidably Orange
I got the O.P.I pink on my pointer and the CG on my ring.
The O.P.I is darker than the CG.
I have O.P.I - Alpine Snow under all of them, and it's one layer of neon topped with some seche ;)
