Place the eyelash curler on your eye and open the clamp. Once the lashes are all in the curler, close the clamp and press for a few seconds. If necessary, repeat the operation and then apply Gentleman mascara to your lashes. NB: The clamp of the eyelash curler tends to get dirty and may cause unpleasant clumps on the lashes. Therefore, make sure to keep it always clean. Replace the rubber as soon as it’s worn out with the refill included in the packaging.
