The Pottery Pots Oyster planter is made from ficonstone, a mixture of cement, sand and fibreglass, making it a sturdy material. The roughed structure gives the planter a robust appearance, suitable for both outdoor and indoor use. The planter is frost resistant, allowing it to remain outside during cold periods without risk of damage. In addition, the product is UV resistant; it is resistant to ultraviolet radiation, which provides protection against discolouration and damage caused by sunlight.
