The Pottery Pots planter from the Refined collection is made of sandstone, a material consisting of a mix of stone powder, polyester adhesive and pigment. This composition gives the planter a soft appearance. The structure of the planter is smooth. Thanks to its frost resistant character, the planter can remain outdoors during cold periods without being damaged. In addition, the planter is UV resistant, which offers protection against discolouration and damage caused by exposure to sunlight. The planter is suitable for use both outdoors and indoors.
