The Tau Rotunda planter is made from fibreglass, a composite material consisting of fibreglass and synthetic resin, which makes the planter lightweight whilst at the same time offering a high level of strength. The structure has the appearance of concrete. 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 risk of damage. Furthermore, the planter is UV resistant, offering protection against discolouration and damage caused by sunlight.
