I really love this product!! Brought mine a while ago, got the nice bright blue colour!! The Blue is nice and bright, and last the whole day. I like the little brush, so easy to make a perfect cat-eye or liner and its tiny so fit in handbag easily. And whats also nice, the lady who sold it to me, said you can use it as a mascara aswell - but to give colour, it does not curl, lenght etc - what all the other mascaras does. So, i have Lash extensions, and sometime i will just dip my mascara brush into this lovely blue, to enhances my own blue eyes :) I have'nt feld the burning sensation...
