The four sets were offering were apart of their SHEfinds giveaway/partnership. Each set had 3 colors in it and out of all four sets there was only one set that I didn't have a single polish in was the Neons set. It turns out that I should have just upgraded my January box because now I really want all the colors for my collection. I got lucky and this set has Fiona, Madison, and Nina. I still need to get two more of the neons form the January box which I will eventually buy but for now these will hold me over until now.
