These uniquely designed risers can also be used as containers. The set of 2 comes in two sizes which nest one inside the other. The large riser/container is 6.25" square and 4.75" tall, the small one is 4.5" square and 3.5" tall. When used as a container, the large is 4.5" deep and the small one is 3" deep. They are made from rubber wood which is 1/4" thick making them very sturdy and well built. Use them for adding height and a touch of natural beauty to any display space. Turn them over and use them as a container for organization and storage. Their simple clean look will fit in with almost any decor. Due to natural variations in the wood, no two pieces are alike. In addition, there may be variations within the same piece due to the natural grain of the wood. This is not considered a defect.
