The Tau Circulum planter is made of fibreglass, a composite material of glass fibre and synthetic resin, which is lightweight and at the same time offers high strength. The structure of the planter is smooth, giving it a modern and sleek appearance. This planter is suitable for use both outdoors and indoors. Thanks to its frost resistant properties, the planter can remain outside during cold periods without being damaged. In addition, the planter is uv resistant; protection against ultraviolet radiation prevents discolouration and damage from sunlight.
