Open kitchen concept came alive ❤️
Love these shelves and recommend to others. They are sturdy with the mounting bracket system and look great. It was easy to install with another set of hands. The material has the look I wanted and there were no missing parts!

Very easy to mount on the wall. Very sturdy with about 10-12 lbs on each shelf. Only took about 15 minutes to hang each one.

Easy to install. Sturdy enough for 2 large rambunctious kitties to play on and look very nice. I was working on a vertical play space for the cats and since these come in many sizes it worked great. I did add grip tape to some.
