This set is made up of 2 floating shelves. These shelves have a shallower depth (7") versus the original floating shelves (12"). These items are made from 100% reclaimed wood. This set is a great deal compared to buying each item individually. The discount has been applied to the set price. Measurements: 5" x 24" x 8" (height x width x depth) We pre-drill holes in the back panel for easy installation. We recommend using dry wall anchors and black screws.
