EndWarts is a safe and unique method to treat warts and veruccas. EndWarts can be used to remove warts from hands, fingers, elbows, knees or verrucas on feet. The EndWarts pen is an effective wart-removing solution that contains Formic acid, which dries out the wart from the inside. The body then gently starts to reject the wart. The Endwarts Pen is safe to use on both children and adults.
