Nice sturdy quality!
Size: 8 Inch, Color: Black
I made my own shelves. Stained the wood & needed brackets. Ordered a variety, different styles. These were the winner. The really added to the look, style of the shelves. Made the shelves beautiful! These reasonably priced brackets make my shelves look expensive and super high quality.

Beautiful! Exactly what I was looking for!
Size: 12 Inch, Color: Gold, Size: 12 Inch, Color: Gold
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
Size: 4 Inch, Color: Black
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.

Cute and functional
Color: Brown, Color: Brown
I wanted something to spruce up a corner in my kitchen and these did the trick. They were easy to install and look great. I use mine for small items and they hold up no problem!
