Love these shelves! Easy to put up, stylish, well made and mounting hardware feels secure. Love the fine details of the included screws and anchors and small tabs to cover screws underneath.

Stylish and affordable!
Color: Grey, Size: 4 Pack, Color: Grey, Size: 4 Pack
These shelves are rey stylish, light and durable! The set came with everything needed to install. The color is just as described. Price is steal and these shelves can definitely be used anywhere throughout the house. I did give it only 4 stars because as you can see in the photos, the underneath was not completely finished. Decided to keep because the price was unbeatable.

One of the best deals available!
Color: White, Size: 2 Pack
Extremely sturdy, good looking and easy to install. I have a couple of dozen feet of assorted lengths in the kitchen, bedroom, living room and foyer. Holding all sorts of antique clocks, audio equipment and cooking stuff from my flours and assorted cornmeals to cases of powdered “lemonade”.
