The structure is executed in concrete, which ensures a robust appearance. This planter is suitable for both outdoor and indoor use. Thanks to its frost resistant properties, the planter can remain outside during cold periods without being damaged. In addition, the planter is UV resistant, ensuring it is protected against discolouration and damage from sunlight.
