For a classic black eyeliner, opt for the Disturbia Liner or Phenomen'eyes Liner Vinyl Black. For a pop of color, use Phenomen'eyes Liner Glitter.
To apply eyeliner, draw a line with the tip of the liner, from the inner corner of the eye to the outer, staying at the root of the lashes. For a thicker result, simply press a bit firmer on the tip of the liner.
Application tip: to extend the eyeliner at the outer corner in a symmetrical way, look down and work on an open eye.
