This set is made up of 2 shelves with wine glass racks. We use high grade pine and add a dark walnut stain with a clear coat for protection. These floating shelves are designed to hold 21 glasses each The shelf above the glasses make a great shelf for pictures or other decor. This set is a great deal compared to buying each item individually. The discount has been applied to the set price. Measurements (each): 36" x 10" (width x depth) We pre-drill holes in the back panel for easy installation. We recommend using dry wall anchors and black screws.
