The Maple Wood Essential Oil Shelf gives you a classy way to display your personal essential oil collection. Each shelf is made of solid maple wood with a bead board back and comes unfinished and ready to paint or stain. The shelf measures 19.5″ w x 20″ h x 3″ d, enough room to store a fairly large collection of essential oils. There is approximately 4″ + between shelves and the top and the bottom has a nice furniture profile edge. The shelf may be attached to the wall via screws through the backing or on the included hanging rail in the back. For best results for fully loaded shelves, and for safety, it is recommended that the shelf either sit on flat level surface, or be attached into a studded wall through the back. (The listing is for the shelf only, no essential oils are included and the picture is for representation only.)
