The White Label planter from the Corten steel collection is made of metal, a strong material that gives the planter a robust appearance. The planters in this collection are made of corten steel, a metal alloy known for the warm, orange-brown hue of its surface. This characteristic colour develops during the rusting process: the planters are delivered while they are in this process and are therefore (partially) rusted. Depending on the weather and location, the planter, which initially has a grey colour, will completely change colour within a few months. This makes each planter unique. To speed up the rusting process, the planter can be sprayed daily with a plant sprayer. In the first few months, the rust may stain the surface underneath; it is recommended to rinse this away daily or to temporarily place the planter on a different surface. Thanks to its frost resistant properties, this planter is suitable for outdoor use and can remain outside during cold periods without being damaged. The finish is natural, which further emphasises the unique appearance of the planter.
