Easy install, wide and sturdy
Size: 10"D x 15.7"W, Color: Brown, Size: 10"D x 15.7"W, Color: Brown
I put these shelves in a strange little cubby that was created in my kitchen by removing the sad excuse for a pantry that was once there. Super easy to hang, I’ve only hung two here and have other plans for the 3rd one. Good purchase for sure. Very sturdy and look expensive, without the high cost.

Great shelves!
Size: 12"D x 35.4"W, Color: Black
These were perfect for what I needed & easy to install with included hardware; looks great and looks like quality item. I like that they will hold 20 lbs so I can change what I place on them with no worries.

Sleek and attractive
Size: 12"D x 23.6"W, Color: Black, Size: 12"D x 23.6"W, Color: Black
While these didn't come in the color I was looking for, the size and price point were just what I was looking for. Installing them didn't take too long and was simple enough, but the end result did seem a little more wobbly than expected. I used them to display mine and my boyfriend's boots, and they held up fine, but I think 22 lbs per shelf would be pushing it.
I was able to easily cover the shelves with wood grain look contact paper and easily trim the excess off with an Exacto knife to get the look I wanted. I'm happy with how it turned out.
