The Pottery Pots planter from the Refined collection is made of sandstone, a blend of stone powder, polyester resin and pigment, which gives the planter a soft appearance. The structure of this planter is smooth. Thanks to its material and construction, the planter is suitable for both outdoor and indoor use. The planter is frost resistant, so it can remain outside during cold periods without being damaged. In addition, the planter is uv resistant; this protects against discolouration and damage caused by sunlight.
