I wasn't necessarily expecting a whole lot from this palette, which cost somewhere around $2.99, I think. Thankfully, I was pleasantly surprised by the quality of these shadows.
The cream and warm medium brown shades both have what I would call a satin finish. They have a nice shine to them, but I don't really see much actual shimmer. They creamy to the touch and have really good pigmentation. The darker brown is a matte shade, and it feels drier to the touch. It isn't quite as pigmented as the other two, but it still has decent color payoff.
The wear for these shadows is also really good. I wore them over Urban Decay Primer Potion for an entire day out with a friend, and the shadows stayed in place and still looked vibrant.
Unfortunately, I have no idea what the availability on these might be or will be in the future. I would be tempted to pick up more if I ever run across them again.
Have you tried any Sinful Colors products that aren't nail polish? What was the quality like? Have you seen them anywhere in your area?
