The Tau Striata planter is made from fibreglass, a composite material consisting of glass fibre and synthetic resin that is both lightweight and strong. The structure of the planter has the appearance of concrete. Thanks to its weather-resistant properties, the planter is suitable for both outdoor and indoor use. The planter is frost resistant, meaning it can remain outdoors during cold periods without damage. In addition, the planter is uv resistant, offering protection against discolouration and damage from sunlight.
