Directions: Wet a cotton ball and tape over the affected nail. Leave in place for 20-30 minutes at a time. If possible, do two times per day. One can cover this application with a finger cot or finger stool (purchased at a local drugstore) so that the medicinal tincture does not drip or get on clothes or bedding. Must be used long-term and consistently to get the desired appearance.
