I was looking at the number of KL Polishes and the number of Colourpops that are on this list (those two together because I believe they're manufactured by the same company), and I would like to note here that Colourpop still has Pixi-lated and the other pastel colors marked down to $3. It's fair to assume they are not coming back once they're gone.
