The Tau Rotunda planter is made from fibreglass, a composite material of glass fibre and synthetic resin that is lightweight yet strong. The structure of the planter is finished in concrete, contributing to a robust appearance. 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. In addition, the material is UV resistant, ensuring the planter is protected against discolouration and damage caused by prolonged exposure to sunlight.
