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!

Cat playground
Color: Black, Size: 35 Inch, Style: 3 Pack, Color: Black, Size: 35 Inch, Style: 3 Pack
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.
