Sturdy, well contructed, and an even natural gold finish. Come with two different wall anchors and brass screws. Installation is easy. Just take your time measuring and drilling holes. I purchased finished white shelves from the closet section of home depot, $7 a piece. Gives them a nice finished look. They measure 3/4” x 11.75” x 24”. The brackets are 12” deep so there is a slight gap at the front but its not noticeable. Highly reccomend.

Find something else

I wish zero stars was an option. The quality was mediocre at best with 2 of the brackets not a proper 90 degrees and the supplied screws do NOT fit the supplied drywall anchors. They are WAY too small. What a complete waste of time and energy. I stupidly was willing to overlook the 2 defective brackets because I really only needed 3 for my shelf. That’s when I discovered that the supplied screws are too small for the supplied anchors. Now I have 6 holes in my wall that need to be patched from the 3 brackets I tried to use. Luckily I was able to back the anchors out of the wall so I could fully return this garbage to Amazon for a refund. Find something else and pass this by. Why can’t anything be easy anymore? At least Amazon has a good return policy but I really wish they would find a way to vett these products better before allowing them to list on the platform. Tomorrow off to UPS to return.
