ColourPop Double Play is a limited edition cheek palette that retails for $16.00 and contains 0.5 oz.
ColourPop Double Play Pressed Powder Face Duo ($16.00 for 0.52 oz.) features two large face powders--a blush and highlighter--housed in a cardboard palette with an interior mirror. The blush formula is supposed to have "long-wear" with a "soft" and "silky" feel that "can be layered for your desired intensity." The highlighter formula is supposed to have "high-shine" with a "buttery-soft" feel that has "high colour intensity." If you prefer your blushes buildable, then you might like the blush in this palette, but if you want true-to-pan color and coverage in one layer, I'd skip the duo. The highlighter had a more metallic finish with some sparkle but a lighter touch can get more subdued results.
In general, ColourPop's powder blush formula is thinner and can feel a little dusty or powdery, depending on the shade, and has sheerer, more buildable coverage, while the powder highlighter formula is much denser, almost to the point where a dense brush is required to pick up a modicum of product. The upside is the denser quality of the highlighter makes it harder to overdo it from the get-go, so the highlighter has a more buildable glow. I wish their blushes had more of the substance that their matte eyeshadows have, which would give them better adherence and overall coverage.
