In terms of pigmentation, in the pot they look amazing, on the eye however they are sheer. To be fair I used them on a bare eye lid rather than over shadow, so the pigmentation would improve slightly but I feel not enough for my skin tone to give me a thick, defined line.
However what you get from less pigmentation is that the texture is smooth and light, it doesn't drag the skin when you apply like some can and they are also not greasy.
To remove the liner a good oil based eye make up remover works for me.
Personally I think they make wonderful eye shadow bases and for those of you who like their gel eyeliners to be more subtle then these are pretty good. I think they might look different on someone with different skin tone, but for me, the lighter colours don't show up as vibrant as I would like.
There are 24 different colours in the range and they are $6.95 each (+ shipping to your country and in some cases import tax) from the Coastal Scents Website.
