The only downside is that I've seen other people reporting that they dry out after a while. I haven't hit that point yet, but I'm really hoping that screwing the lids on tightly will prevent that. Oh and a minor nitpick, the word color doesn't have a u. :( I guess that they didn't change it from the American market.
As you can see all the colors are metallic except for tough as taupe which is matte.
Too Cool - is a shimmery white.
Barely Branded - a shimmery warm beige.
Tough as taupe - a matte brown leaning taupe.
Audacious asphalt - a shimmery gunmetal grey, with green and gold particles, although they don't appear as strongly on the eye as they do in the swatch.
My favourite way to use them is probably as a simple sweep of all over color when I'm in a rush. It is also incredibly easy to create a simple smokey eye with them. The look below was just done with Tough as Taupe all over the lids, then grey eyeliner and facial powder to set, then polish it all off with a coat of mascara and a little powder for your brows. It takes no longer than 5 minutes and can be done with almost any color combination.
