Although we manufacture and warehouse all types of zincs, we don't sell to the general public. All of Tecnoseal Marine Anode's products are manufactured to MIL SPEC. If anyone is interested in saving money on zincs or trying to source a unique type, we can help. We manufacture for many European yacht manufacturers (Azimut, Bennetti, Fairline, Sunseeker, Beneteau, and more). We have a network of dealers and distributors that you can get our quality products from. If interested, just shoot me an email.
