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.

Beautiful & functional
Size: 24x7.9, Color: Black
I was really surprised at how easy these shelves were to install. They look great, and give an elegant, subtle, look to any room. I'm using them in my home office. I plan to order a couple more sets soon.

Great small hanging shelf
These were a great addition to my DYI bathroom remodel. I needed that exact length and it fit perfect for my needs and I was able to install it myself. I’m a 53-year-old woman. I used the other one for a shelf for a candle as well. It holds my oral hygiene caddy well, keeping my sink counter clean.
