Fabulous! I’ve purchased these more than once!
Size: 12 Inch, Color: Gold, Size: 12 Inch, Color: Gold
These are beautiful and the perfect size for the 12” wide boards I use. The lumber isn’t cut to exactly 12” so there is a slight gap in the back towards the wall which I like for cords, and the boards stay in place with bottom screws. These are very sturdy, thick, and solid. I have not had a single problem with any of them. They are easy to install and very functional. Definitely worth the cost. I have purchased a couple of times.

Heavy duty brackets!
Size: 8 Inch, Color: Gold, Size: 8 Inch, Color: Gold
These brackets are heavy duty and came with the correct hardware. They were easy to install, the two holes were so helpful to know where to mark them. I think because they’re heavy duty you can place a good amount of weight on your shelves. The only thing I wasn’t happy with is that 4/69 of shelves, the paint was chipping but it was the perfect gold color.
