FUNGUS KILLER® attacks fungus at its source! Safe, maximum strength solution contains miconazole nitrate (anti-fungal) and iodine (anti-microbial) that go to work on infected skin by inhibiting the growth and reproduction of fungal cells. Just apply a few drops twice a day to help kill bacteria, yeast and fungus on hands and feet. Works with nail polish, too—no need to remove! 1/4 oz. bottle with dropper.
