We hand craft these pots, in Long Beach California, from Cor-Ten Steel. We chose to use Cor-Ten for its rusty coating that protects the metal. We accelerate the tarnishing with a special process that allows us to add many years of weathering in only a few minutes. Once the metal planters reach the desired level of tarnish, we clear coat them so they can be displayed anywhere you would like. Each piece has its own personality since no two ever rust the same. You could enjoy these with a variety of plants, we particularly enjoy putting our favorite succulents, cactus, and air plants inside. Your pot will have a small drainage hole in the bottom for outdoor use. Should you choose to add to your interior with one of our tarnished steel pots, you can plug hole with a small rubber stopper or cork.
