Unlike our coined solid sheet stainless steel manufacturing process, other frames you'll find on the internet are cast brass, zinc or other metal, made in Asia somewhere. Cast products are not clones, they vary in size, form and finish and don't have tabs on the back bottom to secure them to the license plate. (Neither do billet aluminum frames.) All of our 2 hole frames (metal and ABS plastic), have tabs on the back to secure the license plate. We use solid stainless steel sheets as a base material. The reason: stainless steel sheet is not porous, polishes well and doesn't rust. These frames will last! they never rust or corrode. They'll look good for Years. Our license plate frames are made in the USA completely in one plant. By performing every step of the manufacturing process in one plant, we can sell a better frame at or below what you'll pay for a cheap foreign made product
