The Superline planter from the Stiel collection is made of metal, a strong material that gives the planter a robust appearance. The surface has a smooth structure and a matt finish. This planter is suitable for both indoor and outdoor use. The planter can be sprayed in any RAL colour, making customisation possible. Thanks to its frost resistant property, the planter can remain outside during cold periods without being damaged. In addition, the planter is uv resistant, which protects it against discolouration and damage from sunlight.
