i have these in the purple, brown, and champagne colors, and they work great. high color payoff and at $5 each (they were on sale when i got them), they were a good deal too. i bought the brown one first, and since i liked it so much, i went back and got the other two colors!
i use the brown one almost everyday -- it's great for defining my little asian crease :) or as a wash over my entire lid, or even as the darker defining color for the outer corner of my eye.
Very unhappy with this prodct when it comes to expectations of color. I recently purchased this in the black shade and I was dissapointed! The eye shadow was more shimmery than black and it was upsetting especially because i was going out that night and was looking to wear a black eyeshadow and I heard some good reviews on this product. NOT a FAN the pigment in color was no where to be found!
