The Pottery Pots planter from the Refined collection is made of sandstone. This planter is made from sandstone, a mix of stone powder, polyester binder, and pigment, which gives the planter a soft appearance. The structure of the planter is smooth. Thanks to its frost resistant character, the planter can remain outside during cold periods without becoming damaged. The planter is also UV resistant; it is resistant to ultraviolet radiation, which protects the planter from discolouration and damage caused by sunlight. The planter is suitable for both outdoor and indoor use.
