The Pottery Pots planter from the Refined collection is made from sandstone, a material consisting of a mix of stone powder, polyester glue and pigment. This results in a soft appearance and a smooth structure. The 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, protecting it against discolouration and damage caused by sunlight.
