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

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!

They look good and seem well built.

Color: Brown

These are very well made and look really good. They ended up being too small for my need, but that was my fault on measurements. I would highly recommend if you are looking for corner shelves.
