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