I love the rustic, high quality appearance of the Walnut wood grain and black metal corners! This set comes with two thick and sturdy 36 in. floating shelves that attach to the metal parts via the holes in back. The shelves have some weight to them and can support up to 40 lbs. while utilizing wall space for many useful purposes from displaying décor, books, kitchen items, or even storing toys. Installing both shelves was easy and took less than 30 minutes using the provided drywall anchors and screws along with the instruction sheet.  Highly recommend this for home organization, beautiful way to decorate and use bare walls!
