The planter from Pottery Pots from the Granite collection is made of fiberstone, a blend of fibreglass and ground stone, with properties that are very strong yet lightweight. The structure is concrete. The planter is suitable for outdoor and indoor use. Thanks to its frost resistant property, the planter can remain outdoors during cold periods without being damaged. Due to its uv resistant property, the planter is resistant to ultraviolet radiation, protecting it against discolouration and damage from sunlight.
