The Pottery Pots Oyster planter is made of ficonstone, a mixture of cement, sand, and fibreglass, making it a sturdy material. This planter has a roughed structure and is suitable for both outdoor and indoor use. Due to its frost-resistant properties, the planter can remain outside during cold periods without being damaged. In addition, the planter is UV resistant; it is resistant to ultraviolet radiation, which protects it from discolouration and damage caused by sunlight.
