Fungi-Nail Pen goes to work on your toe fungus, eliminating fungal infections on cuticles, around nail edges and tips, and between the toes where if left unchecked it can spread. Fungi-Nail® Pen is formulated with a 25% Undecylenic Acid, the maximum strength available over-the-counter. The clear, water resistant barrier locks the medicine in while the pen applicator targets the treatment right where you need it. First, hold the pen with the brush pointing downwards. Remove cap and on opposite tip of brush (top of the pen) twist 3 times to the right (clockwise). You will not see the solution dripping nor will you be able to tell if the brush is moist since the solution is clear. Place brush against the skin to see that the brush is moist with solution. Use until brush becomes dry, and then follow the same steps. Suggested Use: Instructions: Clean affected area with soap and warm water and dry thoroughly. Apply a thin layer of Fungi Nail Brand Toe & Foot Anti-Fungal solution over affected area twice daily (morning and night) or as directed by a doctor. The brush applicator allows for easy application under nails and surrounding cuticle area. UPC: 053076193510 Weight: 0.38 lbs RKU: WAL582902308
