Handmade Planter Box

This planter is made of a material that is almost pure carbon steel but processed in order to have a protective layer on the surface to make it weatherproof. The surface is originally reddish-brown (resembles the colour of rusting), which becomes darker over time. If used properly, this planter is expressive, durable, and maintenance-free and can stand time in its own peculiar way. When this planter gets wet and then dries out, the rust layer becomes a little thicker, while the underlying solid steel becomes thinner.
