This planter from the Refined collection by Pottery Pots is made of sandstone, a composite of stone powder, polyester resin and pigment. This material gives a soft appearance and a smooth surface. The planter is suitable for use both outdoors and indoors. Thanks to its frost resistant properties, this planter can easily remain outside during cold periods without risk of damage. In addition, the material is uv resistant, which protects the planter against discolouration and damage caused by sunlight.
