The Tau Dolium planter is made from fiberglass, a composite material consisting of glass fibre and synthetic resin that is lightweight and strong. The structure of the planter is concrete, which provides a modern appearance. Due to the use of high-quality materials, the planter is both frost resistant and UV resistant. As a result, the planter can remain outdoors during cold periods without damage and is protected against discolouration and damage caused by sunlight. The planter is suitable for use in both outdoor and indoor locations.
