Like them a lot!
I have only used these as an eye crayon so far. They are long lasting, lovely creamy texture, relatively pigmented and have the perfect amount of shimmer. They look great when worn alone (sometimes creases only slightly when worn like this) but also when coated with the matching shade of eyeshadow. My favourite is the turquoise/blue crayon and I use Essence's eyeshadow in the "Happy Hour" shade to coat. This eyeshadow is closely matched to the crayon's shade because it has a shimmer too. Wouldn't recommend wearing a matte blue as it would eliminate the brilliance of the crayon's shimmer.
