Planters arrive in their natural grey steel state — and over time develop a deep and warm, rust-like patina. But unlike actual rust, this patina is not corrosive — it's purely aesthetic and won't affect planter strength or integrity. You can let the steel weather naturally, or speed it along with full instructions included. Each planter comes with a removable plug for drainage and twin hanging holes ready for installation on a vertical surface. Hanging hardware is not included.
