This water feature starts off looking like any other steel feature. However, after just a few days of use, it will develop a rust-like surface that also has a protective layer. This layer protects against further corrosion, and it is completely unique, so no two features are the same. Complete with a pump, you will be able to get this feature up and running in no time. It is entirely self contained, so all you need to do is add water. - Primrose Waterfall Herb Planter Water Feature Cascade Urban Corten Steel in Copper
