If your looking for a grand-scale minimalist design this Buchanan vase is the one for you! This collection of Planters are cast of reinforced concrete. The material has great weather resistance, less porosity and greater flexibility than other materials, thus allowing these planters to be used outdoors indefinitely and in virtually any climate or location. An applied surface , such as paint, will adhere dependably and these products are offered in a variety of colors and finishes.
