The plant pots are versatile for indoor use as decorative pots and can also be used outdoors. The bottoms of the flower pots have pre-made openings that can be easily drilled through if needed. The plugs included in the delivery can be used to seal the holes again. The pots are made from a mixture of stone, polyresin, and fiberglass, making them extremely robust, durable, UV-resistant, easy to care for, and weather-resistant, even in very high or particularly low temperatures.
