The Dark Side Flash Mat eyelash extensions have the unique feature of having an oval base. This provides extraordinary stability for the technician as the lash holds more easily upright on the natural lash. You therefore save precious seconds with each application. For the client, the oval base helps keep the lashes straight. They therefore need less brushing to maintain an impeccable result. The matte black color provides an eyeliner effect and an even deeper look. * Provides a full fringe/eyeliner style effect. * Quick and easy application: saves up to 4 seconds per lash. * Foolproof application: Flash eyelash extensions are applied in the blink of an eye. * Extraordinary stability even on young adolescent lashes (catagen phase). * Perfect result: they stay straight and do not tangle.
