The Tau planter from the Cubicae collection is made of fibreglass, a composite material of glass fibre and synthetic resin, which is lightweight yet strong. The structure of the planter is reminiscent of concrete, giving it a robust appearance. This planter is suitable for both outdoor and indoor use. Thanks to its frost resistant properties, the planter can remain outdoors during cold periods without being damaged. In addition, the planter is UV resistant, protecting it against discolouration and damage from sunlight.
