Each Fungi-Nail product uses a different style of applicator that enables you to apply the product to your toes without touching the medicine with your fingers. Fungi-Nail Liquid comes in a 1-ounce bottle that’s economical for treating more than one affected area. Fungi-Nail Pen has a pinpoint brush applicator to provide targeted treatment that gets the right amount right where it’s needed. Fungi-Nail Ointment provides a wider brush for greater coverage.
