Onymyrrhe, for Natural Nails, is an all natural myrrh plant extract. Onymyrrhe promises stronger, faster growing nails in just sixteen weeks, or your money back. Onymyrrhe is different from all other Nail Strengtheners. Onymyrrhe is applied once daily, to the matrix - where the nail is alive and growing. It will cause your nails to grow twice as fast and twice as thick, from the root outward, and it's unconditionally guaranteed.
