When buying Clarins products - I know that the quality of the product justifies the price. On application you can feel that the creamy consistency of the pen makes it the perfect, smudge-able liner to contour and blend into the eyes and with the attached brush - contouring is easy!
I love the flecks of glitter in the crayon and the colour is rich and warm and the dry crayon pencil means that the eyeliner lasts and lasts!
