Obviously the intent is for you to be able to not only use the 2 colours separately but also mix them together to create a third shade. I love this idea because this is an excellent space saver for my already overloaded purse!
Even though they are touted to have a moisturizing formula, I find them a bit dry - not matte-like dry but drier than I would expect a "moisturizing" lipstick to be. The upside to not being so moist is the crazy staying power and stain effect. In the top pictures you can still see a bit of a pink tinge around the edges which is from the Cheeky bright pink - I did wipe it off before swatching the Stunner but it wouldn't easily come off entirely. Now instead of a 3-in-1, they are a 4-in-1 - 3 lip colours and a stain!
