This is one of the best palettes ever (and I've tried more than a few). Although the colors aren't flashy, they can help you create a wide range of looks. This was a fantastic find!
The formula is divine. The shades are matte and warm-toned. They're all on the beige-brown side and range from bone colored to a medium dark brown (think MAC Cork). They're very buttery and blend beautifully. They last all day over a primer.
You might be thinking, "OK, that's nice, but what can I DO with these?" The easiest way to use them is by themselves--they can give you the perfect minimal or nude look. They're fabulous on their own. I also use them as base shadows for more *ahem* interesting shades (like some of my Fyrinnae sparkly e/s). I'll put on lid and crease colors from this palette and then apply something with some drama or shimmer over the lid color for an instant, somewhat-subtle-but-still-fun look.
This isn't cheap and you might not be wowed by the colors, but this is a great versatile palette that you shouldn't overlook.
