This planter and stand set is made of metal with a dual-tone finish. The inner diameter of the planter at the narrowest part is 21cm so this will fit any of our large plants without a problem. These planters are all hand made in a rustic finish with intentional minor imperfections. As all these bowls are hand made there are minor differences from one to another and each one is slightly unique. Intended for indoor use. Can be used outside but needs to be protected from extremes of weather. Colour: Copper/Black
