The planter by the brand Den Daas from the Doppio Bordo collection is made of terra cotta, an unglazed pottery. The structure of the planter is smooth and the finish is natural. The planter is suitable for both outdoor and indoor use. There is a drainage hole in the bottom, which allows excess water to be easily removed. Terra cotta is naturally not completely watertight; therefore, it is advised to use a liner to make the planter fully watertight.
