The Pottery Pots Ridged planter is made from ficonstone, a mixture of cement, sand and fibreglass, making it a sturdy material. The ribbed structure gives the planter a distinctive look. This planter is suitable for use both outdoors and indoors. Thanks to its frost resistance, 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.
