We are a husband and wife team located in northwestern Arizona, the sole owners, designers, manufacturers, and distributors of the Four Nines Fine Colloidal Silver Generator System. This business and our products were seeded in a dream, and built upon the strong belief in the powers of colloidal silver, and also a firm belief that this beneficial product should be available simply and affordably to everyone. We supply ONLY 3rd party UL Certified, 9999 fine, 12 gauge silver rods in our systems for the purest colloidal silver that can be produced at home with any generator. We are highly customer service oriented and dedicated to providing our valued customers with the simplest, most user-friendly colloidal silver generators available on the market. We are experienced sellers, having sold over 1000 units from September 2015 to present. THANK YOU FOR CHOOSING FOUR.NINES.FINE!
