An ultra-fine eyeliner whose formulation has a high pigment content for rich, matte colors that do not smudge. Its sophistication lies in Thermo-Sensory Technology, thanks to which the solid lead warms up on contact with the skin and turns into a fine film. It is waterproof and lasts up to 24 hours. The tiny diameter of this new generation pencil allows lines of the highest precision and even fine dots to be placed between the lashes.Application: twist out eyeliner tip about 1mm (1 - 2 clicks) and glide along the lash line. Close carefully after use.
