Three sizes of matte spheres in different shades of grey-black with hints of iridescence offer a lot of sleek sophistication. The color of each piece in the set could vary and all pieces will not match. Alone or in combination with other components, use tons of them! The ten-piece set includes 2 large (3"D), 4 medium (2"D), 4 small (1.5”D). Five colors in the collection. Wall Play™ is a Gold Leaf Design Group trademarked collection of over sixty unique, three-dimensional hybrid components that allow the creation of custom textural art almost anywhere. Think outside the box and create your art without borders or frames. An installation can involve many individual components or a simple loose clustering of a few. The quantity used doesn’t dictate the overall size of the completed installation. Be adventurous by repeating one shape, combining multiple shapes, clustering, and layering. Creating and enjoying your style is most important. There's no incorrect way and it's easy to create your WOW. *Caution, sharp screws. Product is not made for use by children.
