Remove the cap of the pen. Twist base with brush pointing upward to saturate brush. If you do not hear a click, turn the other way. First time use may require up to 40 twists to initiate product flow. For subsequent applications twist only as needed to saturate brush.
Apply Fungi-Nail® around the cuticle, on the skin along the edges of your nail, and underneath the tip of the nail where accessible with the applicator twice a day.
