These quality wood shelves are ideal for turning unused wall space into a functional and decorative area. The use of red oak wood provides strength and durability to the shelf, while the gray paint and polyurethane coating give it a modern, polished look that can complement a variety of interior design styles. The shelf appears to "float" on the wall without any visible brackets or supports, thanks to a hidden mounting system. The mounting system consists of two metal brackets. This is a set of three shelves.
