ColourPop Climax is a very cool-toned, dark blue with a matte finish. It is a permanent lipstick that retails for $6.00 and contains 0.0352 oz.
ColourPop Climax Matte X Lippie Stix ($5.00 for 0.035 oz.) is a slightly muted, deep purpled-blue with cool undertones and a matte finish. It had mostly opaque color payoff, but it could have been richer for true, one-stroke opaque coverage. The texture felt smooth and glided on without dragging, but the thinner consistency seemed prone to emphasizing lip lines and natural texture of my lips. The color lasted for six and a half hours with slightly uneven fading overall. The biggest upside is the non-liquid format makes it easier to apply around the edges.
