Great, but bring your own inserts.
Size: 24x7.9, Color: Black
These work great, easy to install. Happy with them. Only problem was the instructions say don’t use the include inserts on wallboard, which meant I had to go out and purchase my own. That’s OK, because I like to use inserts I trust.

Love the shelves, great quality and design. They are very sturdy and perfect for my need. I ordered wine glass holders from Amazon and attached them to the shelves. Impressed and amazed at the look.

Great shelves!
Color: Grey, Size: 55 Inch, Style: 2 Pack
This shelf is lovely--simple and modern. My handyman said it was easy to install AND made a note to buy it for his own rental units because he said the internal supports were very sturdy. Fast delivery and exactly as described--and the price is nice, too.

Good size and quality
Easy installation, been up on the wall for several months now and they're exactly what we were looking for. Pretty sturdy, good quality. First order of these came broken but they replaced them no problem.
